Sheena - it sounds as if her "dad" and his family will harm more than help. I am sorry you have had to go through all of that. Sometimes there is gov't sosered respite care. Churches may be able to help. Please don't make any rash decisions since you are not feeling well right now. What about summer camp? There are some state sponsered camps that are relatively inexpensive and could help out. There are a bunch of resources out there, please check into them, and I hope you find something that works out for your needs. I am holding you and your little girl in my thoughts and prayers!
