I feel like a rollercoaster. My boyfriend is on a 8-months exchange program and it's being really frustrating not to be able to talk to him 24/7 like we used to do. 
I can't sleep until it's like 3 a.m... and then I sleep until it's one p.m. Can't be productive, but also can't stop feeling anxious and jumpy all the time. It's like I need to be in constant motion and stimulation, but can't do a single thing on my own. I know it's not fair with my family, they need me and I have responsibilities. I have a job, and a life, but I feel like my life keeps cycling since I'm 14 and I'm stuck in this endless void of feeling euphoric at night and late afternoon and feeling really bad in the mornings. I can't get myself to brushing my teeth, I can't clean or cook or prepare my classes. I feel frenetic and like I have this crazy amount of energy that doesn't get up into my brain and I just can't burn it out. 

Please, I know this isn't a place for diagnosis, but can anyone help me understand what the heck is happening to me? It's been 3 weeks, I can't stand it anymore. Please!
