Hello LalaLoveLiz,
I am so very sorry for your situation, I don't have any advice that will help, I just wanted you to know that we are here and available to listen.
I am lucky in that my parents have a Irrevocable Living Trust and it has provisions for stripping my parents of control of their Trust and commitment proceedures built in, my mom has been an alcoholic for over 40 years and my dad had the Trust Attorney build in some safeguards.
Best of luck to you,
Bill
