stress and pain

I'm really stressed out. I have a job and going to school full time. I just moved into the dorms. I've been lifting too much stuff walking too hard and fast and going going all day long. I've had a head cold the last week. And my head and shoulders have been hurting a lot llately. I don't know what to do because I need to be a full time student to live here and I do not want to move again. I also need to get more hours at work. When I'm up and about it doesn't hurt as bad. I'm going to try my dance class tomorrow I'm just worried it will be too much for my back. At least the teacher was my teacher before and when I got sick so she's understanding. I also need to start physical therapy again. And on top of all that I need to pay my way past due bills and clean up some odds and ends at the old place. I'm just hoping that when my stress lessens then my body will feel better. I worry that I'm either doing too much or I'm getting worse. Both of those are bad cuz I'm on my own now and I have to do all that. I can't afford not to. I also can't afford to get worse. I drove a half hour to work every day and it's bad posture the whole time. At least I'm away from people stressors. Maybe I'll start combating one stressor at a time and see if that helps.
