My biggest fear (and my children's, too, unfortunately) is my passing away from MS. I'd much rather it be from natural causes like old age (100 or so). When I go to lay down, I think of death and it makes me wake back up.
I love my family, friends, pets, etc. I used to not want to live, but now I have so much to live for. The anxiety that thoughts of death cause me is bad. I try to relax. I just don't want to leave anyone behind....
