Well...
If this is the best option for your mental and or physical health, good for you.
Toxic people can be parents too. People love telling people to excuse toxicity because it's a parent. Some parents rightfully earn their spot in the bushes. With that said, I'm glad I don't know what that feels like.
I was one of those people who believe(d) parents/family can do no wrong...and when they do forgive them...swiftly.
My beliefs were further entrenched as I witnessed middle class black families & my own thrive. I was brought up & taught Baptist doctrine. Specifically, 'Honor and obey your parents all the days of your life...'
It wasn't until I became non-denominational & got from around my immediate family (my mom was overprotective and rarely let me out of her sight) and began to see dysfunctional moms/dads - neglect, obvious favoritism of other siblings, resentment, verbal abuse, critical but hardly praised, etc. In my own family my mom (daddy's gone, RIP) was way, way tougher on me than my brothers. Although she didn't play the radio with none of us.
It was then that I recalled how no one hardly ever referenced the biblical quote - 'Do not provoke your child...'
Although I'm aware that there are men & women who have no business procreating, I still have a soft spot that they carried/birthed the child. That counts for something - as many people who say xyz about their parent(s) I hardly see them say they wish they were never born.
I've joked several times on here about parents winding up in nursing homes...all alone. I'm not saying it's always right but I understand.
OP,
Family is crucial & extremely important (above all else, imo). I hope that your relationship with your Mom can be mended soon.
