Echelon,
I wouldn't worry about your psych. He'll just raise an eyebrow, shrug, and just say to you that you have a lot of work to do together to make sure this is right for you. You've laid down a fairly definite plan,matin reasons behind it, so he'll just work with you.
Family, as always, will assume the worst. Just be prepared to spend time explaining things. If they were supportive before, they will be again, if you have clear reasons for what you are doing.
