Oh my gosh! Your mom and mine must have been clones!
My mom has always been jealous-- so much so that she wouldn't let any of us girls learn anything around the house-- so she could tell us what failures we are and she would get praise from outsiders of how wonderful she is. She gossips and badmouths each of us in hopes to get us in fights-- not anywhere near the stereo-typical "nurturing, unconditional loving mother"...
So sorry your mom was similar to you-- it's hard to have been raised by such a mom.
The psychologist I am a sporadic client to--(

)-- has always said this: "The crazy one is NOT usually the one sitting with the therapist-- it's the one that won't ever go!"
I think it says alot about you in that you are able to love your mom. I truly don't think I love mine.... but then there was traumatic physical abuse as well as emotional so maybe it's more than I'm able to cope with.......
Thinking of you
