I am so sorry you and your mom are going through such a horrible time! Your mom is in no shape to speak for herself or take part in her treatment. Apparently she is not getting the right treatment for her which, unfortunately, can take a lot of experimentation. I think you should find out as much as you can about her diagnosis and what they think is going on. Take as big a part in the decisions for her care as you can. I am not sure how it works when a person is no longer competent to make decisions for herself but you should have a say I would think. And don't forget to get you help with coping too. This is not something you should have to handle alone. I will say a prayer for you and your mom tonight.
