Hello Skystar,
I understand your thoughts about AA since your mother hasn't had a drink for so long, but you may call and ask... perhaps they have a referral program as well.. It is good that you have a therapist as well... and you are very aware that you are pinned between two strong, controlling personalities.. awareness is 90% of the healing, so it is said.
Working through this will give you a strong sense of empowerment.. there is a part of you within that has the strength.. I have a sense it was crushed when you were little, trying to be a good girl and do the right things by your mom, perhaps for her approval...
But ultimately you are in control of you.. and I pray you will gather the strength you need to take your stand...
Please keep us posted...
take care
