These are just the consequences of her condition, I am very sorry that you have to witness your Mother going through this, must be difficult and I can only pray she gets better.
That is what we can all do. Pray. Pray that God does something brilliant for your mother and gives her back the life she deserves. She will be okay I believe that, you now just have to believe it too. She is slowly losing energy and is giving up, be strong for her and maybe it will rub off on her? Make her feel loved and better! Make her feel normal most of al, putting emphasis on her condition might make her feel more overwhelmed and hurt. You just have to be strong for her, it can be hard but do it for your Mother.
Trust me, whatever will happen will happen for the best! Good Luck and God bless.
