Welcome to the forum. I didn't watch your rap as it's silly o'clock so can't be blasting out sound at this time! Sounds like a great way to get all your thinkings and feelings about diabetes out in a very creative way!
Feel free to post wherever you like, there is a youth section and we do have some peeps around your age post there but don't feel confined to just post in just one area!
14th Jan, coming up to your 1 year anniversary then! i was diagnosed 12th Jan 2009 so coming up to three years for me!
