At the end of the day applications always depend on others after you
send the form or do the interview, so being stressed wont help. In other words,
focus on what you can control, sleep, eat well, and send in more applications.
I personally was in your situation a year ago, and I just gave up completely
and went and lived in the forest. Now I am friends with another really cool and
probably autistic older guy who was also in the forest.
He spent years of his life working for the system, they stole his inventions
so he gave up also.
Modern society sucks, its a lose lose game unless you are a sociopath.
You can also like, make small things and sell them, like bits of software,
or art, or teach your interest. Thats what my uncle did.
We are better off self-employed, even after the interview they aren't gonna respect you.
