Need to rant / maybe some advice.

Working remote is hard.
New company, remote on boarding. I feel like my coworkers are robots, and I'm being tossed into the deep end with minimal guidance.

The codebase is so unnecessarily complicated, its impossible to read. I've been trying to figure out how things work for a whole month, still not sure.

My mentor that is supposed to help onboard me is a robot, and answers questions in a somewhat acceptable manner, but it still feels like a lot of "figuring out" is still left for myself.

My other work partner that is also a newbie like myself is also a robot - doesn't talk or ask many questions whenever we have a sync up meeting.

The codebase is huge and feels quite overwhelming, I don't feel like I got a team "with my back", I don't enjoy work as much as I have before, I barely do any coding (mostly reading code and trying to understand how everything is working by setting breakpoints and debugging tests that take foreeeever to run), and some days I'm seriously considering cutting my losses and jumping ship just to save my sanity.

Am I paranoid? Am I just dumb? Should I just suck it up and be happy I have a job? Is this how Remote work is supposed to feel like? Why does it feel like my soul is dying?

Anyone in similar situations, or who can give some insight/advice/etc, I would highly appreciate it.

And this is supposed to be a good company too from the reviews. I don't know how it can be so crappy in reality. Did I make the wrong choice joining? Should I jump ship sooner rather than later? I've only been here about a month or so, and maybe its too soon? Halp!
