I Don'T Even Know What To Do Anymore

I'm in this weird limbo where I'm watching my life fall apart no matter how hard I try to make it work. I don't really know what to do anymore. I'm sick and tired of being such a burden. It's like I try and fail at everything, but the one thing I'm good at most likely won't get me anywhere. Maybe I truly am just unrealistic in my expectations or maybe I am broken. Defective in some way. I used to be tougher, now I can't take anything at all. I am mad at myself for becoming so inept. I hate letting everyone in my life down. I wish, wish, wish... that I could make everything how it used to be. I wish all this was a horrible nightmare. I wish I could go back to the day I stopped being me and prevent what ever broke me from happening. I wish.. but wishing.. is just that.
