Can’t sleep

I can’t sleep until like one o’clock anymore because I don’t know. I just stay up at night with all of this energy and I feel like I need to go fight somebody or run a few miles. I can’t though. I have to stay at home and try and sleep. It happens during the day too, I’ll just feel cooped up and I have to do something, anything at all to get rid of the energy. I’ve literally never had problems like this before and now it won’t stop. I get angry for no reason and I start to freak out and all sorts of crazy shit happens to me. I’m not on any drugs by the way, well, I am taking 20 mg of fluoxitine (Prozac) every night but that’s all. I’ve been taking the meds for almost a year now and have never felt anything like this before. I don’t know what is happening to me. If somebody knows or has an idea please tell me. I feel like this could send me right back into the hell I was in just a year ago. I need somebody to be there. I need an explanation. I’m going to be checking this post compulsively for the next few days just in case a new comment gets posted. That’s what I’m talking about. The things that used to occupy my time now don’t cut it. They just don’t. I need something to help me. To just chill me out because living like this is just fucking crazy.
