Aproudbyg, I concur with those who have asked youto report or to seek assistance from OHEL or a similar group. THis is abuse, and your mom has serious problems, even if you think they are tolerable or under control.
However, if you are determined not to advise police or seek assistance beyond this forum’s advice, I urge you to document EVERYTHING. Write down what happens, when it happens, and if you have a bruise ch’v or worse or ripped clothing, take a photo. If you can record a violent incident with your phone, even if only audio, do it. B
But this is only back up. it isn’t a substitute for seeking help, which I again urge you to do. If you only described one incident with your mom, I’d concur that anyone can have bad judgement and a bad day. But what you describe is systemic, and aside from the danger to you and the ongoing psychological damage you are receiving, you are also enabling her to continue her unacceptable behaviours. Please consider an outside agency or the police.
