Perhaps waiting in saying about the abuse until you are fully off the drugs and can think clearly (though you seem to be very clear already).
Can you explain to people your needs? i.e. needing your naturopath, therapist, nuerotherapist and explaining the great stress that big and small changes can cause most Aspies to feel.
If you're off the drugs and are able to explain to them (authority figures/law people) that the wrong placement could be as damaging to you emotionally as staying in a place where you are punished for being you, they might then give greater thought as to where to place you?
Truthfully I don't know what is the best course of action for you. What I've said is what I think may be best for your situation, from the information that you've given me. I can see how this will be hard for you whatever course you choose and you'll be physically on your own, I'm sure you'll get emotional support from people here, I'll certainly try to give emotional support to you. Take care.
