Stressed out

So I'm so stressed out right now. I have alot going on with Summer School, paying bills off becoming a new Aunty, helping out and Working two jobs. I need to relax but I don't have the time. When I'm not doing all those things I'm struggling with some issues I just can't shack. I'm trying really hard to figure out my life and the people who are in it. Right now I have been off and on with this guy...(MatT) he is really great and really horriable at the same time. Sometimes he treats me like crap and then wonderful. I don't know what we are anymore. I know I have love for him but I''m tired of all the shit. He has puet me through the ringer.........The hardest part of leaving this alone is that he has two beautiful children...that I have been around since one was one and one was in the belly...Now don't judge but they were not together when we met...SO he says....I want a more and I'm trying to make it work but its just to much for me now..................AWWWWWWWWWWWWWWWWWWWWWWWW I just don't know what to do...............
