what your father is doing is wrong in every sense of the word, I don't know where you are in the world, but here it ios classed as abuse and is illegal! Please let your T know about his behaviour, and that of your mum, they are probably the root of your needing to see a T in the first place!
T's should not be blaminbg things on Satan, because that is a personal belief of theior own, not a proven reality. is there any way you can change T for one who does not bring their own beliefs into the session?
