Going down hill and why?

The Klonopin is making me sick to my stomach and weak, I have no energy all day and every time I stand up I get an extream head rush. I've isolated myself from every body and sleep most of the day, I feel there's no reason to be awake, I have no enthusiasm for anything any more. I've tryed slitting my rist a few days ago until some one came into my room, now I have a bad red mark on my rist that hurts and itches. My friends noticed my wrist and think I should take therapy, also because I shared something with them I've never shared with anyone before, my unwanted and uncontrolable thoughts and my lack of be able to have a happy or normal thought, only terriable thoughts that make me ague with myself. my mind is always running a million miles a minute. I don't know what to do, I don't know why this is happening to me or why. Am I going crazy, or am I just wierd.
