Here lately I have been a lot more emotional than normal, about everything! Not only that, but I randomly just started feeling depressed a few days ago. I have been clean of self-harming for about 7 or 8 months, and life has been going just fine. Me and an ex recently got back together, ( Broke up in early 2013 because of relocation ), and I'd say I've been even happier since I have him back. According to my teachers, I have been more hostile, angry, and just wanting to butt heads with everyone all the time even though in my eyes I am acting like I always have. I have noticed that I am hardly getting any sleep.. The previous last three nights I have been falling asleep and maybe getting 30 minutes of sleep then spending a whole 1 to 2 hours trying to go back to sleep, over and over all night. I have also been having weird dreams, and my short term memory is off a lot!

Is this normal? What is causing it? How do I help it go away?
