Another MS friend died

I logged on a little bit ago and got an email from a lady that sends info on MS to me. She was one that I used to chat with in an MS room on AOL, but now I am on MSN. She forwarded an email from a friend's husband notifying us that she (his wife Kathy) died in her sleep from some heart problem like a clot. I guess she was bedridden and in a wheelchair. She had no previous heart condition. It scares me because I am in a wheelchair and sleep a lot. "They" say that MS doesn't kill you, but I disagree. I started crying because I made her a couple of floral arrangements and we used to talk a lot on AOL. That makes two internet friends dead from MS.
