What did I do wrong? Why does he HATE me?

well, you seem to have loved this guy pretty well, and after all your depression you had a great time and now you find it hard to be alone again..well, the only thing you can do right now is to forget all these incidents and start a new life.. you seem to be e pretty nice person, why hurt yourself....there is nothing wrong in your part.. may be you got angry and said something bad , but still, you will have to forget everything and lead a new life.. Find good friends who care about you..easier said than done, i know..but this is not the end for you..and also stop comparing yourself with everyone...you seem really nice, hope you get good friends..good luck..
