depression affects everyone with cf its natural though cos cf people are carrying a heavy burden around with them most people dont have to face .I have suffered from it as well and it really does ya in also i think what really triggers the deprssion is the isolation factor cf causes ,ie spending a lot of time on ya own via the treatment and so i feel this creates a subconscious inferioty complex in people and more so in boys as well where the they arent as strong as they should be (lack of absorbtion etc) ie ive been told iam only about 80% of normal ie muscle tissue is not there cos lack of absorbtion etc also the headaches and tiredness cf causes affects the abilty to socailaise so yeah cf is a shite thing to live with but the way i see it any normal person would be affected living with this disease
