cystic fibrosis chick

Hey everyone, just wondering if there is anyone out there in my situation. I'm a 30 yr old female with cystic fibrosis, I'm pancreas sufficient so I'm one of the lucky ones that can maintain weight without any help. My only problem is I maintain it too well considering I was at 220 pounds 3 years ago. Fortunately my weight has come down to 150 pounds now and I'm hoping to lose another 25 pounds. Having a really low lung function (currently sitting at 40%) cardio is very very hard, so I work a bit slower than most, but I get the job done I'd really like to meet others in my situation or people with health problems in general who have to take things at a slower pace so they can keep pushing me and giving me the motivation I need at times and also looking for any tips or advice they might have to offer
