It exists! My mom's had it since I was four and because of it her immune system attacked her own body. And she lost sight in her eye for a long time, plus it made her unable to feel texture. It doesn't kill you that fast though, it depends on the way it affects you. Plus, a company has come out with a medication for it recently. It's called Lemtrada

I had two hamsters, one was brown named Eric. Then we lost him and got a new one. I then named that one Eric 2 (don't ask, I was obsessed with The Little Mermaid at the time), he was white and was the worst creature that walked the Earth. Soon after Eric 2 came we found Eric 1 and put them in the same cage. Long story short, Eric 2 killed Eric 1 and I was scarred for life.

hopefully he died pain free.... ╥﹏╥
