B2Y, I get it too.
This caused a minor meltdown for me last month. I was tired of being strong and misunderstood since I know there are others in worst predictaments. I was sick of all these "invisible" symptoms. I felt like I could sympathize with the moles in the old arcade game of "whack-a-mole".
But between some counseling and a lecture from the neuro (after he told me I was still stable), I bounced back. My hubby took it in stride, and told me that probably every once in awhile this will happen.
I'm learning to accept my new normal and not obsess about what I used to be able to do. It's not easy and has been a bit of a battle not to compare, but when I manage to do it - I feel so much better about myself.
Venting is good for the soul, and glad you did.

Hang in there.
