somethings not right here

I have this new wonderfully messed up problem. Could someone tell me why I get to feeling so depressed whenever I come across something I like- whether it be music i like to listen to, food I like to eat or anything of that sort? Could someone explain to me why I find myself on the floor of my closet, crying without remembering that I even entered it? this is all so backwards. I have no drive to do anything that has to get done except the fear that if I don't do it, there will be consequenced that I don't want even more than i dont want to do the work- thus the severe procrastination I have found myself engaging in. And the only thing that doesn't get me upset is reading. Well, that part makes sense, escaping to another world, however messed up that world might also be, takes my mind off of my own life. not that my life is even all that bad, so i dont know why i want to escape it so badly.
