No Problem Android Studio, just get completly fucked up. It's not like if i would need to finish this course before thursday, no i definitly have time for this shit.

So, my current company builds a ERP system hand has a far to complicated database with one k tables and over 2k procedures. I started working there 3.5 years ago, well, first 2.5 years were educational. But I was mostly doing support work. From time to time I was tasked to do some interfaces ( around 15 currently I think) but since a few month I am just completely fucked up and don't know what to do. I still don't really get how this fucking huge database is supposed to work. I have 2-3 interfaces alto implement at the same time. Then I should create a app to allow users to stamp the personal and assignment times. Also I was tasked to create a html5 webpage ( never did something like this before) for also stamping times and some additional data to create a service report for customers on the fly. And finally I should create a asp.net based website for a dashboard overview which should be customisabke by our customers, which I also never did before. In the meantime I also have around 10-15 support tasks a week, and I don't see myself getting anywhere near finishing anything. But I am getting constantly approached by the boss and my team leader for not really getting anything done, even though they have no idea what the other one told me to do. And my boss has no idea if time management, he asked me how long a feature of the app would take and I told him at least two days and somehow he told my colleague I would be done in 4 hours. So currently I am permanently stressed and slightly depressed and I have no idea what to do, and I am just afraid of losing my job, because I am not able to finish my tasks.

I hate it when you ask a question on so and include the complete code and everything and just get a -1 and no comment or anything.
What the hell. I doing wrong, please tell me !!!
