Hello nogutsnoglory.....a nurse with Crohn's here. Do remember, my pet, that this disease refers to the "poopy parts," and no one likes to address that part. Plus people are dopes. Selfish dopes. Alas. They don't care enough about you, they care about themselves and you're just no fun.
You remind them that health is fragile. That, by jove, it could happen to them! Nope, they want to avoid all notion of anything but a good time and that is a very consistant mode of behavior, so do not take this personally. New friends are on their way, real flesh and blood friends who will be more aware, not be intimidated by sick people. This world is made up of people who avoid the physically ill, the mentally handicapped, the terminally ill and the dying. Oh, Lord, do they flee from the dying part. I so hope that you can cultivate a sense of humor, and take this time to develop yourself. To take a class on line even, to take an art class of some type for an hour a week that requires less emotionally than a group of friends who like hyenas to scream with. I don't even know how old you are, I should read up on it, but you sound young or new at this game. Hanging out with "sick" people is the best, second to hanging out with dying people, so I have been very fortunate in my life to be able to have a job that allows me to do this and to learn. My patients taught me everything, how to live, how to accept the inevitable, how to grow, and how to die with grace. Seek fun in other places and you will find it and you won't feel awful ALL the time either! Then you won't want them around. Trust me.
