Having read your posts, it sounds like you need counselling to help you deal with this process. Or life coaching, whichever seems best. But start with another person who is there to listen to and advise you, who is a professional. Then see a primary care physician and explain how you feel physically. Have some blood tests, find out what your health is and see if you need any meds. You are looking for external validation for your suspicions about your mother and you won't find that on here. If she won't agree to see a physician or a lawyer to sign power of attorney, then this can be done in her absence if she is diagnosed as incapable. But take care of yourself first, so you have the strength to deal with this. Good luck.
