iam 20 and have found as a result of serious problems with my stomach and to a lesser degree my lungs my social life has suffered.I think what it is is all the physio gives me headaches and i only feel about 85 % .Also a lot of stomach problems as well cramps dont want to eat leaves you feeling down. Similary the constant physio which i do 3 times a day roughly about nearly 2 hours a day saps your energy and you dont feel like going out with freinds etc.At the end of the day we are only human and not robots does cf affect other peoples social life
