Madalot, that sounds so like me. teased for being a weakling, no stamina as a child. As a young adult, friends got into distance running, I collapsed after 200 metres. Stress convinced A&E that I was in shock, I was actually delivering a friend who was really hurt.

And now I am being told that as I am seronegative and have no ptosis, then I can't have any Myasthenia. At the last meeting with the Neuro, my partner did ask... "CMS?" "No not possible." says the expert.

Trouble is I am getting worse, and at a worrying rate. So I have no idea where it will end.
