The only time I think I'll regret my decision is when I'm a little old lady. You'll be surrounded by your children and grandchildren and hopefully your great grandchildren and I'll be eating my pureed alone with no one to visit me.
Dugong,
I believe here is just as much chance of you ending up with alot of family & friends around you when you're a little old lady as someone who has had kids. I worry about this as a CFer too sometimes, but then I think of my aunt Loretta.
She is 70 years young and CF. Her husband passed away about 20 years ago. Ever since I can remember, she's gotten so many invites to friend's & family's parties throughout each year, she can barely make it to all of them. She also has cousins & friends her age that she frequents the casinos with. She works PT at a fun job that she likes to keep herself busy, too.
For me, she's the most fun relative I have & no event would be the same w/o her. We just threw her a 70th surprise party, too. If she was ever ill or needed help, we'd all be there. It's not just familial obligation, it's the kind of person she is that makes her so in demand.
I know the circumstances aren't the same for everyone who is CF, but I know lonliness is not the inevitable fate of evey CF person. Hope this helps if you're ever worrying about getting old!
