Quick! I don't know whats wrong but I just have this feeling?

I feel like I need to run and scream and break something! I'm tired but at the sam time it's impossible for me to get to sleep. It's like there's something inside me driving me crazy and I need to do something to get it out! I can only think of two things; cutting myself (and I really don't want to do that again) or go running but it's like 11 an snowy outside and I know once I start running I'm not going to be able to stop! Every inch of my skin is like irritated and feels itchy and its just gah! And no I'm not on something!
