No. You'll learn to live with the memory and with help you may be able to better handle your reaction to that memory. At least that's what they tell me. I'm so sorry you're dealing with this now. She is (was?) a shameful mother.
You most likely will not forget your mom molesting you but you'll learn to get over. You need to get over it so you can move on with your life.
I don't know. Is she in jail? tell us more..... ( and, sorry)
Probably not, You can try to not let it ruin your life. I would suggest group therapy with other victims of molestation
Probably not. But maybe your experience can help you protect someone else. Or could be a personal testimony that things can get better if you want them too. I was molested by my cousin, so I know how it can affect a person. While the experience was horrible, I don't regret it because it made me who I am today.
You will only get over it if you want to. It's a pretty deep subject to be asking about but everything takes time.
