Hello 2Fatigued: Welcome to NeuroTalk!
Hopefully coming here to NT can be of some comfort & support.
I trust you will find the time you spend here to be of benefit.
Since you've already found the Myasthenia forum, I don't need to provide you with a link to it. I believe you'll find a lot of information here as well as support. Best of good fortune with your Long Term Disability application!
