The only advise I have, is to seriously consider your mood when making a decision to move away from your support system. When deeply depressed, I often think about moving away and see it as my only option to get what I want (which is usually to die without burdening anyone) I was once told not to make any major life decisions when depressed and I think that is one of the best pieces of advise I've ever received. I hope you figure out what works for you.
