Oh no Mandyfins... first of all, I'd like to say that I think you're brave for opening up here. You've helped me and many others so many times yet this is the first time that I've ever seen you talk about yourself. Thank you for trusting us with this part of your story.
About your mother, well, I agree with Petunia that she probably is addicted to it in a disorder sense. I'm sure you've already read
this but just in case.
On one hand, I want to say that it would be best if you did an intervention.
On the other hand, she's both elderly and someone who you have had bad experiences with, so there is a part of me that wants to protect YOU and keep a distance from her.
I don't know what the right thing to do is. Please just know that you have my support no matter what
