Anyone familiar with autonomic nervous system dysfunction in MG?

I've had myasthenia gravis since '97 mainly affecting eye muscles but in the past swallowing and speech has been affected occasionally especially when tired. The main issue daily is getting super fatigued after doing the simplest things.

Last few years I've noticed I'm less able to cope with situations which I primarily put down to menopause ... however it's only gotten worse not better. After researching it appears MG patients can be affected by autonomic nervous system dysfunction which I think was masked pre menopause but now post menopause don't have the buffer anymore. Does this sound familiar with anyone? Any suggestions re supporting nervous system as it's like I literally can't cope with even basic family discussions without getting overwhelmed stressed and irritated..
