Haha, yeah...

I did the classic overachiever route and finished my thesis pretty fast, focused on a specific career. Then still ended up with a shitty full-time job, so took on three more jobs and started a nonprofit. All that still got me exactly nowhere. I was ridiculously stressed. One time I didn't sleep for 3 days and had to check in to the hospital.

Hopefully this offers some comfort. The things you consider mistakes, are the things I wish I had done. Even spending more time with my parents. So perhaps nothing is so serious :)

My "nuclear option" was immigration. I sold everything and (just barely) got a business license in the developing world. I'm basically Ozymandias from watchmen, but less fit and I don't own tights. Also none of my friends are blue. Splicing genes and splitting atoms, I will admit to though.

Anyway the point is, what matters is what happens next. I don't recommend immigrating to the developing world (it's acutely distressing), but it's surprising how much we can influence the outcomes of our lives if we radically commit to a course of action. If the exact details of your course of action aren't optimal (or even borderline insane), I think that's OK, it's being radically committed to improving your future that matters. The context isn't exactly irrelevant, but I think it's secondary.

So no need to stress. Better to spend that energy doing. Anything reasonable will do. Start a side hustle, learn programming, design websites, learn to do taxes for yourself and others. Degrees are OK but I don't value them any more personally. Get used to starting at square one over and over -- it's a good habit and you will eventually know how to do many things. People who can do many things are rare and valuable.
