I just want to feel okay..

I officially broke things off with the guy I have feelings for.... He and I are over... and I feel horrible... He's so upset... I'm just not happy... I need someone who can be tougher for me and positive and who I don't feel like all I do is fuck up with.. And he's sooooo emotional and negative about EVERYTHING.... And when I try to help him I feel like I make it worse.. and we argue about EVERYTHING... My feelings for him just aren't enough anymore.... But now I feel empty.... I just wish I could disappear for a while.... Now what....? I don't know what to do anymore... Everything seems to be going qrong.. I'm shutting don't to the point I don't want to speak at all anymore.... maybe I should try it.. talk as little as I can get away with for a while... Maybe I won't be able to cause so much drama.  Really running out of options here... Tired of feeling so lost all of the time...
