Haven't read everyone else - but yes!! you are so normal!!
I was dx'd in 2001 and the giant concrete block of fear hung over my head for 2 years. I worried that having trouble going up the stairs was a symptom (nope - I was just fat!

), I imagined that I was having weird sensory issues, but it turns out that I had sat in some mortar while tiling my bathroom!

I'm a worrywort - I can imagine a symptom like noone else!!
Good news is that it does go away! It did when I started hanging out on Message boards and talking to other people. Once I saw lots of people living well despite MS, the fear started receding. A counselor helped a lot too.
Don't fret, you'll get there. And despite getting a stinky dx, you've now got a whole new group of friends
