They won't. These are common worries, but it is highly unlikely that a therapist would ask this - or expect you to be over it by now. Contrary to popular opinion, time does not heal all wounds.

I'm sorry to hear about what happened to you. I certainly understand why this would traumatise you, what your mother did was terrible and she is now refusing to take responsibility for it, so you're stuck with all the pain. I think it would be a good idea to try therapy.
