I'm so happy to hear that your daughter will be moving in with you. I wish I had an answer to your question. I'm not sure anyone can entirely answer that question...I've asked it of therapists, never really received a satisfactory answer. Hmm. I think that stress most definitely can worsen mood issues. Then it all gets to be a vicious cycle...mood probs/stress/more mood probs/stress is worse. It seems that something needs to break the cycle, whether that's medication, movement, time away, or whatever works.
