Meeting other people with the same condition
Young people mostly like to spend time with people their own age for obvious reasons, more interesting, more fun etc. Finding somebody your own age with a similar condition can be a very positive thing although not for everybody. The good things that it might bring are sharing stories, asking and giving advice and even just relaxing and having a good time. It also lets you know that you are not the only one!
Ask the doctors or nurses at the clinic if they run a group for young people, or if they could introduce you to somebody. Another way is to contact the patient group website as they may also be able to help. Better still offer to organise a meeting for other young people at your clinic!
