OnwardandUpward, I've been reading what you say on the support thread and I'm so sorry you have that sort of mother and are now estranged with your son.
I've also done therapy because I know it's affected me a great deal. I also unknowingly at the time exposed my children to all of it because even though I didn't like how she treated me on the surface, underneath I felt I deserved to be treated badly, I didn't have any knowledge or understanding of the fact that, mothers can be abusive, controlling, neglectful and enmeshed. I thought I wasn't loved because I didn't deserve to be. My fault.
I've struggled with anxiety, depression and illness my whole life and doing so as a mother myself is terrifying. I didn't know how much I was impacted by my upbringing until I walked away from it.
My mother told me so many times that she didn't like me that now my biggest fear is one day my children won't like me. Not estrangement, I'd rather my children walked away from me than simply put up with me, to be a chore, unlike and unwanted again.
I just hope as you say that personal growth and willingness to change will get me there, not just where I am loved and wanted but where I am able to feel all the time that I deserve to be.
