Hey wild cat your trying to push yourself more than you can and hopefully you will get the help you need from your Dr if your falling then something is wrong
With MG rest is also our medicine as well I'm lucky I have to totally concentrate on each step worse is passing people or if I take my eyes off were I'm walking so close to falling over so far been lucky not to.
Our symptoms are different to each other which is confusing
Good luck with getting help!!
