Hateing life right now.

Ok so I'm venting alittle bit here. I'm getting really really tired of being on a roller coaster with my emotions. I've been doing really good till last night and for some reason i was in crisis mode again.?!?!? Then this morning I was in a great mood happy and smileing, etc. As the day goes on I'm all depressed again. Not in crisis mode but still pretty bummed. i HATE this!!!! I've been like this for so long and I'm SOOO freakin tired of it!!! I just wanna be happy again!! If i even now what that is....
