i'm a dentist with crohn's disease. i was diagnosed in undergrad and went through dental school with it. i was lucky to be in remission for most of my time in school, but i had a nasty flare during my 4th year. i found that managing stress was the most important thing to help me feeling better. i tried to get as much sleep as i could, keep up with my medications and try not to stress about school. i kinda accepted early on that i needed to get through school, not ace it and that helped a lot too.
do they have you on any medications? once they get you into remission, it will definitely get easier.
what year are you? if you don't mind me asking.
i agree with what the poster above me said. make sure you sign up for the asda disability policy because that will carry over after graduation. that has been the only disability insurance that i've been able to get. the prices are reasonable. and it's not much...but it's something. i never qualified for disability even with years of remission. also, consolidate your loans as soon as you get out to a 30 year plan so you have some time to pay things off if you get a flare up that puts you out of work for a while. i built a nice little rainy day fund, but i've been lucky and have only missed 6 weeks of work due to a surgery. the nice thing about dentistry is that i've been able to work as much as i can. right now, i'm doing 3 shorter days and a long one because that's about what i can physically handle. i'm not raking in the dough, but it's more than enough to live comfortably as long as i don't lead an extravagant lifestyle.
i'm sorry you got diagnosed with such a nasty illness. it does get better from here though. if you have any questions or anything, don't hesitate to drop me a pm.
