Welcome Carol!
Do you take any medication for the blues and sadness? Do you get medication for the pain and other symptoms? Just because you have MS you should not have to suffer.
I hate to complain to my kids and family too. So I don't. I used to, but it gets old, and no one likes to see tears and hear complaints all the time, I can't blame them. I wouldn't like it myself. Plus they don't really understand.
Get some medication, punch a pillow to two, write a journal and rant on it, and come her and talk to us. We listen and we care.

Nice to meet you.
