Keri,
I am so sorry that you have to go through this. I hate that saying too. I want to throttle people who toss it around.
For me, dealing with this comes in spurts. I'll think I have a handle on everything and all of a sudden it's like I was Dx'd yesterday. (Latest icky reminder: MS Walk) I think things like this have to be accepted/digested/assimilated/whatever in pieces. It's been well over a year for me and I'm still waiting for the "Sorry, made a mistake. Here's your life back" phone call.
Hold tight to your friends. Mine have been invaluable through all this. If you want to talk about anything, PM me.
