Have you actually been DXed with MG yet? If not then the Dr. should ask a bunch of questions and do a tensilon shot test and order other tests to be done. You are right to be upset with your Dr.s office, it always boggles my mind that Dr.s staff seems so "cold" to patients. As for your vision getting worse since working makes sense as stress or activity or heat makes symptoms worse. I hate that I am no longer working {I was working part time} it just seems lately that eating wears me out..LOL, but hey summer will be over soon and cool weather shall be returning with, hopefully my strength.
