Everyone deals with the hand they're dealt in their own way...in their own time. Yes, there are worse things than MS. And people with those "worse things" find their own way of coping. I try really hard not to compare my situation with others......each is unique in its own way.

Maybe try and look at Copaxone as a good thing....something positive you can do to slow the progression of your MS.

I'm sorry your sisters situation dominated so much of your life. It's time to concentrate on yourself now....and what you can do to make your life better and healthier.
