hi Ashley and welcome
I would say take the job you love and run with it for as long as you can.
personally I went back to work (teaching skiing!?!) in the middle of my first (only, so far) relapse, and they made the accommodations I needed. since then i have worked to achieve new certifications and the only reason I'm not on snow full time this winter is b/c i blew my ACL at the end of last season.
definitely read as much as you can, so that you can make informed decisions about the options. (I started out pro meds but changed my mind after reading up - but that's just me)
there are TONS of resources available to help you manage stress. one aspect, nutritional support, (my fave!) is key for ms patients and anyone else who wants to manage stress well and have a healthy immune system into the bargain.
have any of the docs sent you for nutrition testing to see if you match a typical ms patient in the nutrient status sense? if so, do you have your own copy of results? if not, that's a good piece of information to have at your disposal to help guide your day to day decisions about food.
gluten dairy and sugar avoidance can protect but not necessarily heal a fragile immune system. gluten avoidance can prevent the nutrient drain associated with consumption. but it can't replace chronically depleted nutrients, if those are in the picture for you.
not to worry - lots of info here on good nutritional support for ms, for stress, for lots of things
again, welcome to the forum!
