I'm so sorry you received negative results.

I have lots of memory problems with my MS. Luckily they seem to come and go, though my brain has slowed down considerably and I can't multitask at all anymore.
It's my fear that the effect MS has on my mind and hands is going to put my on SSDI way too soon. But I guess going on disability at any time is too soon.
I feel for you and wish you and yours all the best!
