I am so sorry about what you are going through now. I know how rough it is and what a tailspin it can be. Take time to breathe and be at peace with all that is going on around you.
I understand the toenail issue. Some things are just harder to tackle than others. Heck it is hard to cut one's own toenails (LOL)... So - good for you overcoming that fear. I am sure her nails look beautiful!
I hope things settle into an easy-going routine for you. I wonder if her weight loss was due to the rehab center's food. I know Dad would never eat their food but when he got home he would eat like a horse. The food was bad and atmosphere depressing. He would always cheer up when he got home.
Just know my thoughts and prayers are with you now. I wish the best for you and your mother. Remember, take care of yourself too.
