Overcoming abuse is very difficult-esp.childhood abuse.The child finds it difficult to talk about it & is often threatened against doing so .Since no one else also talks about it, the victim presumes she has been singled out,& feels all the more guilty,thinking it must be something in her.All this fear,guilt & shame suppressed for years naturally take their toll-which has happened to you.But please realize you were helpless & a victim,you did not ask for this to happen to you.
How are things now?Are you an adult?Are you safe now?Is your tormentor far removed today?Are there people around to help you?
If circumstances have changed for the better you can rethink your strategies--no?Talking about it to a trusted person will help you,do you have such a person near you,apart from the Ts.
It appears from your post that the worst is behind you-certainly you will be OK.
