I dont care about the psychological "abuse". It isn't much worse than psychical. Psychological (you mean blabla by others) is just fun. Let them talk... Or attack back... I know, it's difficult as a child to talk back to stronger/older People, but the time comes.
Psychical (beat) is also not bad. Then I "felt" something. I felt pain, only for a short time, but it was something. All their blabla like "you're a nightmare of every family" or "you are stupid" dont matter for me. Also the pain not, because I was beat next day also for doing something "wrong".
When you're strong enough, nothing must heal, because nothing is destroyed.
