My heart goes out to you.
I don't have anyone in my family that has that, but we had an employee diagnosed a few years ago. It is a terrible diease. She went off the deep end and started calling customers in the middle of the night, as well as was completely unreasonable during the day. I can't imagine having to deal with this at home. I think its going to be important for you not to lose who you are in all of this. I wish I lived closer we could go out for a cup of coffee.
