I finished the last test of my entire degree yesterday. It was online (thanks covid) with a time limit and I didn't manage to finish all questions because I spent too long on some when I should have moved on. I thought I would feel relieved, proud, be celebrating being done with uni, but the anxiety won't stop. Couldn't sleep and woke up with a stomach ache because of it. How do I stop beating myself up about all the things I did wrong and stop stressing about my grade?
