There is so much I could say, but won't. I'll try and give a reply. Until you can exhibit tough love for yourself, and put the "mother" aside and out of your life (tough in a way because every child needs the love of her mother) you will only be harmed over and over and over again. It isn't your fault. Fault? Really, you really think that, because you had hope of change, or of being strong enough to totally overcome evil?

The last you will experience directly from those who are still around and plotting evil is to cut them out of your life. I'm sorry. They won't change. You must.
