Please stop hon, you have been given all the advice and opinion we can give. No one sees ALS in you, not your doctors and not those of us here who know the disease.
You are really doing everyone a disservice by posting on like this. You won't convince us and we have to look after our dying friends here.
I know you are scared, but honestly, we are dealing with the reality. Join a general health anxiety forum if you need to talk about your fears.
all the best
