What I believe is (sounds trite) that when one door closes, another opens. If you think hard enough and long enough, you MAY come up with a different career than being in an elementary classroom all day 5 days a week, which is soooo hard on the body and mind of even a marathon runner, in my opinion. If you like to write, maybe you can write at home? Or start a business you can run from home? (I like that... run...). Your MS might not limit you "other than" migraines. Maybe soon they can be controlled. And you won't be bothered with any other MS symptoms. If I were you, I would have a Plan A, and a Plan B. Plan B may not be on the tip of your tongue at the moment. But your brain, especially while you are sleeping, will be creating ideas! For example, another idea is some kind of teacher training. With your Masters done, you are to be congratulated!!! Your school district can give you some ideas for your Plan B: what can I do with my Masters besides teaching in a classroom setting? Best of luck!
