Disclaimer: I realise it's kinda dumb to ask for advice on internet. I probably won't follow it. I can say that I wouldn't write this if I didn't see how shitty other threads here are as my excuse. I probably just want someone to talk to.
So here we go.
I am almost 20, I live in a poor eastern european ex USSR country. I am trying to set my life straight, but, well, I have a fuckton of mistakes to correct. I am stronger than average here, smarter, too, I dare say (or is it daresay? would someone correct me PLEASE?). However, I only have 3 people I can call "friends". I don't seem to be able to make more - I either discard potential friends as not being good enough or am not accepted for unknown reasons. I was bullied at school, I was/am socially retarded (not a virgin, but that's a different story, and believe me, healthy relationship is not what it was). I probably don't believe in myself - I compensate for this being extremely picky and snappy with others. I train in martial arts and keep myself in a good physical condition (maybe slightly more fat than I'd like to be, although not overweight - I'm thinking about going for gothninja look) - but that's 90% because I was bullied and am compensating, I think. I'm a student at one of the state's best universities, though my marks are barely enough not to get thrown the fuck out. TL;DR - I'm fucked up, how do I unfuck myself?

Also, if I get a green card, will I be able to serve in the military and get a free ticket to educationland?
