Hi, I’m sorry that you are going through this. Honestly, my best answer is to get her into a dementia care community. This probably won’t get better, and it just sounds like someone else would have an easier time caring for her. Don’t feel guilty: this is just what you need to do for your mother, and also for you. You deserve good care, and so does she, and she’s not going to get it when she’s resisting all of your help.
