I was hit by a car today and just found out the other driver does not have insurance
Oh no, that is so unfortunate and so unthoughtful of the other driver! 
Yes so I am unsure about the whole thing if my insurance pays will my rates go up etc
Yeah, it shouldn't affect your insurance. Since you were not at fault. But who knows how the whole thing will turn out. 
That is what I find concerning the uncertainty of the whole thing, nerve wracking!
That would be, I hope your insurance takes care of you!
