I work at a tech company and get paid well. If they fire me it will be hard to find a job that pays me as much. I am doing my job ok-ishly. I don't think that I am naturally as talented as some of the people I work with, but I am doing ok, and my manager promised me he will tell me if there's something I need to improve or get better at (and he hasn't done so, so I guess I am fine).

But this experience is insanely unenjoyable. I always feel like I don't work well enough. That I don't know things that I should know, and that I don't finish projects fast enough. It makes me constantly anxious and angry at myself. Sometimes I forget to do something and I am really hard with myself, but I should stop giving a fuck. I am doing my job well enough and those fuckers would never feel slightly bad firing me if they had to.

I just don't know how to not give a fuck.
