Crohns disease

Have had crohns disease for over 35 years now and am thinking of getting my medical card. Any suggestions since I have never smoked a cigarette or anything in my life and am scared but now at the end of my rope with no where to turn so help. Am on Maui and need to also know if there is such a thing on Maui as caregiver although I would not need them for more than about an hour once a week if that makes any sense but please give me some direction since I am totally green and have never even experimented with a drug stronger than an aspirin and I am totally terrified now. Thanks Peace.
