Alright Green Ive also got some advice to you. I feel im pretty similar to you or was (still kinda am). When I was in highschool I also talked to people and had aquatencies but spent almost all my time alone outside of school. I was also a pretty shy/nervous guy. I also played video games all day, and i played and still do play Yahoo chess too! Also had suicidal thoughts etc etc etc. I also got very interested in psychology. Basically me and you are very similar. Seriously just dont worry at all about these problems. I mean of course try to make an effort to be friendly and nice, and if you get invited somewhere dont pass it up. But all these problems I PROMISE YOU will slowly dissolve away with time. Just remember you still have alot more growth mentally to happen. I know that hards to realize because I never saw that in myself because well i guess you just cant, but trust me you do. So I would recommended do your homework, learn to learn, dont get down on yourself, and always above all just use your common sense. Use your common sense with the way you act, but even more importantly they way you think of yourself, dont let negative and idiotic ideas manifest inside you. alright good luck with life and remember you may seem trapped mentally sometimes but seriously you will be fine
