Sasha, I think you just gave yourself the best advice yet !
Try if possible, to pospone your decision about moving. You dont have to tell anybody, anything. Just mention you are rethinking your situation.
Put yourself first and foremost !...and protect your piece of mind and your sobriety at all costs !
Best to you and yours. Remember we love you and we're always here for you...even when "Family" bails !
