Hello i need some advice on my son.He has cf since he was 3. hes keeping very well and he just turned 18.The problem is hes a lunatic.we live in a run down area and he is in with the worst crowd imaginable.They constantly break the law and just laugh about it.My son doesnt bother with his medication as he says he says he doesnt need it.I admit he is very healthy for someone with cf but i know that wont last long if he keeps this up.He doesnt even bother with his appointments anymore.Im not sleeping at all these days i just worry and worry.Last week i found a large amount of cash inside a pillow under his bed and theres all sorts of thoughs running around my head.Probably not the kind of stuff this site deals with i just need to get it off my chest.
