You are the only authority on your experience. You don't need your mother or anyone else to validate anything.

Emotional abuse could affect you in every single way. There's no way to turn back the clock and know what would have been different. Life is surely profoundly changed.

I lived in denial of my own abuse for years and that was made very easy because there wasn't a scar I could point to, there was no physical evidence, just emotional problems. I was sexually and physically abused by a very clever psychopath who never left a mark on me. It still twists my stomach when I think about how sneaky he was, it was as if he knew how to obscure reality itself, deny me my own suffering, denied me the ability to see what he did as abuse. If I didn't finally follow my gut, follow my heart, I never would have begun to heal.

It's hard to honor your feelings when you're stuck trying to figure out "Was this abuse? Is that what this was?" I was there for 30 years. Trust your gut and don't worry about what mom says. You have a journey of healing laid out in front of you and unfortunately perhaps she isn't ready to be a support in that journey.
