Yeah, you're right. Since I wrote this post, I've been going to the gym and trying not to give a fuck about some things, and it seems to be working well.Cam I'd suggest some regular exercise (~30 min/day), some meditation (real meditation, regular, studious meditation, ~30-60min/day) and forget about these guys recommending pills.
Sometimes too many people around me causes me to get anxious: I talked to way too many people on Friday, and felt so drained that I started mishearing what people were saying and saying stupid shit in response. Was not at my best and started to get anxious about how I was being perceived by the girlfriend and her friends. Told everyone I had work to do, and I got away from everyone by going for a nap and doing some homework. Turned my phone off so no one else could ask me where I was on campus. Felt much better after that.
I just need to be able to handle situations and understand the real worth of worrying. I need to understand that people aren't going to think you're incompetent the moment you say one stupid thing. Just things like that.
