My mom wasn't always good at it. She was very abusive for most of my childhood. She was having seizures constantly and it fucked with her behavior super bad. We didn't know about the seizures for years because they don't present like you'd imagine a seizure presenting. Once she got them under control, we worked together to repair our relationship. It wasn't easy, especially because her seizures cause memory lapses. She legit didn't remember a lot of the stuff she'd done. I actually had to bring in folks we know as witnesses to help her realize what she put me through.

I'm so sorry your mom is shitty. I hope some day she'll be able to change.
