I can only speak from my own experiences but I've found no matter how I approach the subject with my mother she gets on the defensive and either tells me it didn't happen, I misunderstood it, it was for my own good or it was my fault.

If you feel you need to talk to her about it then you should but just be prepared that you might not get the answers you want.

She emotionally abused and neglected me, sure I had a roof over my head but I never had the love only a mother can give. You shouldn't feel bad, emotional abuse often leaves some very very deep wounds.

Have you tried talking to someone else about it? I refuse to talk about my childhood with my mother because she has her account and I have mine, both are very different.

Sorry you're feeling this way.
