"I just don't know what to do with myself."

I don't know what's going on with me again. I just don't feel like having any human interaction right now. All I seem to want to do nowadays is just draw, smoke pot, Facebook chat with Skosh, watch DVD's, listen to music and communicate with my friends through text messaging only. I feel bad because Amy called me Sunday but I hadn't woken up yet and I didn't feel like hearing about how wonderful her life is and how happy she is.
I feel isolated and alone and I know I have a habit of pushing people away but I just can't do human interaction right now.
I'm sick and tired of all this fakeness and these facades people wear around me. At least I'm real and I may act like a bitch and act selfish all the time but I really can't help myself. I feel like shit; if I knew how to change I would in a heartbeat but I don't and I can't change. I hope this rough patch goes away soon. I don't want to continue to push Nick away it's just hard to enjoy life when there's nothing much to enjoy and everyone around you is so god damn happy and chipper.
