I've had crohn's for about
15 years. My relationships are long since gone. The only people I have contact with are my parents, and occasionally some people at my dog park. The good: I don't have to deal with crappy fair weather friends. The bad: it can get kind of lonely. However, at this point, I'm kind of used to it. I can at least depend on my parents, so that's cool.
EDIT: Thought I'd also mention that I live in a retirement community with my parents. It's a little strange never having contact with anyone younger than my parents. Luckily, I grew up in a neighborhood that was mainly old people, so I guess it wasn't a huge adjustment. Initially, people kind of eyed me with suspicion. Even the dogs at dog park
. But now they seem to have accepted me, even the young-people-hating dogs (except for one chihuahua who still hates my guts for not having grey hair).
