If I could erase the horrible suffering from my mother's past, I would 100% for sure. Because that's where a lot of the pain came from for me. I guess erasing my memory of her pain and the resulting pain that passed down due to her behavior would have the same result because I wouldn't remember. But then she would continue to tell me in the present about all of the abuse and how no one loves her so....

Honestly, I would just rather none of it ever happened to her. And I had a functional mother.
