You know I acted the same way as you did just slightly different. Instead of being a complete introvert, I started to be a totally different person because I wanted people to like me. Everyone often says:"Just be you" or "Go talk to someone about it" but there was no one you could really turn to, am I right? At least that's what happenend to me. What I can tell you is, not everything is like highschool. When you go to college, if you think of going, I don't anybody will really care about the way you are, you'll always be invited to the parties and the stuff that'll be happening. Most of all, if you go to a college where you really want to go you will find other people who are just like you, because they are there for a reason just like you. The thing is, I always made a fool of myself. Now I'm always being confident. I'm complimenting girls on how they look, ask them where they bought the t-shirt that they wear and stuff like that. It's not that simple but be always confident and nice. I really can't tell you how to find REAL friends, but I can tell you how not to be alone in your class or how not to have somebody that you can do your project with: Just be overly nice, confident and always make the girls feel special and beautiful when they are with you. That's all I can tell you, but believe me it won't change anything if you start to get depressed that's just bad for your parents and for yourself. I know, I've been there. Things are always changing, just because you can't make friends that easy doesn't mean you should give up trying. Try what I told you, maybe you find friends like that, it worked for me haha what you can do also is try a different style. Just change your
appearance completely. New hairstyle, new fashion style, start making accounts on instagram, tumblr, twitter so that you won't feel left out anymore and maybe you could do a twitter account where you speak about those things that you experience now, so that you can help others who have the same thoughts as you. Nothing bad about trying something different, makes you feel way more confident also :) Let me know if you tried out anything I told you and if it helped xoxo
