The stress of change

I recently had to move from a nice rented house in a good part of town to an apartment that is a reck (there is mold everywhere, no heat, and broken windows in the kids rooms). I made the mistake of not looking at the place before moving in. We did not have much an option though. My old landlord was selling the house and the new apartment was the only one in town with three bedrooms. I ended up having a breakdown for three days where I curled up and cried all the time. I felt like it was all my fault for bringing my family into such a miserable place. Ever since the move things just seem to be going down hill more and more. My exhusband lost his job and is trying to start his own business. It is going very slow and he has not been able to pay child support. I am having a really hard time trying to pay my bills never mind trying to give my kids all the extras that they are used to. Christmas is something I am trying to not even consider right now or another breakdown will occur. Due to all the stress that is in my life currently my fibromyalgia has been acting up more than normal. I feel like I am in a never ending spiral. I get depressed and my pain increases, I am in pain and my depression gets worse because I can't do all that I want.
