Mamade3,
Thanks for your update. It sounds like you have done what you can for your mom and now it's up to her to take the next steps.
One thing I would like to suggest, and please don't think I'm saying that YOU have a problem, but it's this-- you have been very deeply troubled and burdened by your mom's issues. Her treating you this way (depending on you to be the only person to listen to her, but not getting further help) is very concerning to me. You might choose to find someone to talk with yourself, when you are ready, about making healthy boundaries with your mom. Please know this advice comes from a caring place-- you should not be put into this position of having to be the only person she will allow to care for her. She is *choosing* not to talk to anyone, whether she can admit that to herself or not. I think your comment about "I would be furious if one day she started to talk to my girls about (her) childhood" is a good place to start with your mom-- that she is not to discuss this with your children.
I hope that in time, she will get help, or that you will find your own place of peace around this.
