I understand you so much. A sexual/physical abuse is always considered in society yet an emotionally is very difficult that you find someone that really thinks you are saying the truth.
Society is hard with woman/man abused, saying sometimes even that woman doesnt want to work or even that her is a coward, it is not! Only someone that have suffered this knows the fear of living with an emotional and hard mom that suddenly is fine as bad without knowing why. And that s the important, it is your mom, so you never think that a mom wants to hurt you, which is still more confus.
You grow confused, guilty with a very low esteem and you never know why, why and why. Because of society says you that a bad mom have to hit you...

But the good...you are not alone. You can find people who can understand here.

Hugs.
