Heya i have this friend who is 14 that has cah and he thinks that hes the only one and is down alot of the time and i was just wondering if theres anything that i could do for him. He takes alot of time off school being ill and has reasently been throwing up blood and fainting. I am getting very worried and was just wondering if this is quiet normal from someone with this illness and if there is anything that maybe i could do to make him feel abit better about himself. Thanks alot.
