My first Project is finally ready to be deployed on prod server.... Nervous.... How u guys cope with this stress?

I may not be a dev... (learning in my off time though, best thing ever) but I have been responsible for the computer system validation, requirements definitions and planning of a new piece of software that will have a major increase in effeciency for a division consisiting of over half our companies employees.

For months it has been a painful process. I have had night terrors, immense pressure on my head all the while thinking we are getting to that final goal (live deployment), and the light at the end of the tunnel has just seemed to be getting further and further away... Like a donkey chasing a carrot on a stick.

After all the grey hairs, stress and drinking I am finally going to deploy this thing to the live environment tomorrow. Funny thing is its the part of this process that managers are stressing about and I am here like... Oh wow my Friday just got a whole lot better

i was hired to join a team of old devs (40+) in an unnamed European country "yay goodbye 3rd world it's time to enjoy the quality of life" assist with enhancing already existing software and creating new solutions.
prior to my arrival most things were slow and super buggy, looking at the code base it shouldn't be a surprise, amateur hour everyone, logic implemented that is not needed, comment driven development, last time code review was done back in 1996. lots of anti patterns.
i swear there is a for loop that does nothing but it loops through a 100+ elements list, trunk based development with tfs since git is "not really needed"
test projects are not there.
>enter me an educated fool, with genuine passion for the craft and somehow a decent amount of knowledge.
>spent the last year fixing stuff educating people on principles and qualities.
> countless hours of training and explaining. team is showing cooperation, a new requirement comes in to develop with react.
> tear my ass creating reusable shit and self explanatory code with proper naming etc using git with feature branching, monday is first deployment day.
> today a colleague was working on an item submit a pull request and self approve it
> look at the code..... WTF the dumb fuck copied and pasted the whole code from different kendo components but somehow managed to refractor the name to test component, commented out all the code that he didn't use did the api call directly from the component, has 2 useeffects that depends on the a fucking text box changes for no reason, no redux implementation, the acceptance criteria is not achieved, and it doesn't work it just look right.
> first world country shit cannot scold, cannot complain, lead by example.
>asked him why you did this, the response was yeah probably i shouldn't have done that, i really didn't understand anything in the training but didn't want to waste time!!!!
> rest of the team created a different styled disaster with different flavors they don't even name their shit the same way.

fellow developers I'm stuck in a spaceship with a bunch of imposters, seriously i never cried in my entire life now I'm teary and on the verge of a break down.
talk with management "improving needs time" and offers me to join a yoga session to release the stress as if reaching nirvana would deliver shit on monday.
i really don't know what do is this a rant, is this a cry for help, I'm not sure, any advice is welcomed.

Tl;Dr Im the one of the few in my area that sees sftping as the prod service account shouldn't be a deployment process. And the ONLY ONE THAT CARES THAT THIS IS GONNA BREAK A BUNCH OF SHIT AT SOME POINT.

The non tl;dr:

For a whole year I've been trying to convince my area that sshing as the production service account is not the proper way to deploy and/or develop batch code. My area (my team and 3 sister teams) have no concept of using version control for our various Unix components (shell scripts and configuration files) that our CRITICAL for our teams ongoing success. Most develop in a "prodqa like" system and the remainder straight in production. Those that develop straight in prodqa have no "test" deployment so when they ssh files straight to actual production. Our area has no concept of continuous integration and automated build checking. There is no "test cases", no "systems testing" or "regression testing". No gate checks for changing production are enforced. There is a standing "approved" deployment process by the enterprise (my company is Whyyyyyyyyyy bigger than my area ) but no one uses it. In fact idk anyone in my area who knows HOW to deploy using the official deployment method. Yes, there is privileged access management on the service account. Yes the managers gets notified everytime someone accesses the privileged production account. The managers don't see fixing this as a priority. In fact I think I've only talk to ONE other person in my area who truly understands how terrible it is that we have full production change access on a daily basis. Ive brought this up so many times and so many times nothing has been done and I've tried to get it changed yet nothing has happened and I'm just SO FUCKING SICK that no one sees how big of a deal this. I mean, overall I live the area I work in, I love the people, yet this one glaring deficiency causes me so much fucking stress cause it's so fucking simple to fix.
We even have an newer enterprise deployment. Method leveraging a product called "urban code deploy" (ucd) to deploy a git repository. JUST FUCKING GIT WITH THE PROGRAM!!!!..... IT WAS RELEASED FUCKING 12 YEARS AGO......

Please..... Please..... I just want my otherwise normally awesome team to understand the importance and benefits of version control and approved/revertable deployments

I got a contract with this schools to build a student portal,

I do all the needful and the project whatever guy insists that I use their current shared hosting to host this MERN stack application.

first of all, cPanel is my least favorite place when it comes to deploying, I actually dont do deploying I just hand it over to whoever is the IT guy there.

I discovered there's no provision for nodejs in their current plan, I go through all the stress of contacting the shitty customer support and the process of squeezing out useful information from them.

I'm only doing this because the project whatever has refused to pay me until their site is deployed. throughout the process of creating this project I had setup continous deployment on heroku and netlify and I had to beg this guy to look at the changes and review them.

well, today I asked the former guy that built the current site for the login details to the schools dashboard on the hosting providers site and he says he used his personal details for it, according to him projects from other organizations are there too.

I swear I'm going to loose my shit, freelancing sucks

So I work for an IT consulting firm (web development) and was hired by a customer 7 months ago for coaching Git, implementation of VueJS on the front-end and fostering teamwork with devs who'd been in their solo comfort zone for the last 15 years.
I asked for confirmation multiple times on whether they were sure they wanted to go through with a bigger investment in front-end. Confirm they did, multiple times.

After half the team's initial enthusiasm faded (after 1 month), the 'senior' of them who's worked there for 18 years on a single -in the end, failed- project got a burn-out after half a week of showing up (without doing actual work) from the stress, and started whining about it with management that has no technical clue whatsoever. This and other petty office politics lead to the dumbest organizational and technical decisions I've seen in my short 5-year career (splitting a Laravel app that uses the same database in two, replacing docker container deployment with manual ssh'ing and symlinking, duplicating all the models, controllers, splitting a team in two, decreasing productivity, replacing project management dashboards with ad-hoc mail instructions and direct requests).

Out of curiosity I did a git log --author --no-merges with the senior's name on the 2 projects he was supposed to help on, and that turned up... ZERO commits. Now the dept. hired 3 new developers with no prior experience, and it's sad to see the seniors teach them "copy paste" as the developer's main reflex.

Through these 7 months I had to endure increasingly vicious sneers from the IT architect -in name only- who gets offended and hysterical at every person who dares offer suggestions. Her not-so-implicit insinuation is that it's all my fault because I implemented Vue front-end (as they requested), she has been doing this for months, every meeting at least once (and she makes sure other attendees notice). Extra background: She's already had 2 official complaints for verbal abuse in the past, and she just stressed another good developer into smoking again.

Now I present her my timesheet for January, she abuses her power by refusing to sign it unless I remove a day of work.
Earlier this week I asked her politely to please stop her unjust guilt-tripping to which she shouted "You'll just have to cope with that!", and I walked out of the room calmly (in order to avoid losing my nerves). She does this purely as a statement, and I know she does it out of bad faith (she doesn't actually care, as she doesn't manage the budgets). She knows she wields more power over me than the internal devs (I am consultant, so negative reviews for me could delay further salary raises).

I just don't know how to handle this person: I can't get a word in with her, or she starts shouting, and it's impossible to change her (completely inaccurate technological) perception.

Just finished deploying to production. Now to find a mate and release some endorphins.
