How can they help OP, though? If it really is that obvious that it was OP who reported it, I don't see how saying "Hi, we got an anonymous report, we're here to investigate" would suddenly remove any suspicion by OP's family that it was OP who did it.
Depending on where OP lives, disability programs can be very difficult to and backlogged to get into.
With that said, it sounds like OP is planning on leaving anyway.
That sounds like therapy isn't ideal then... the first goal should be to help, not to punish... lol...
