Hi im 19 years old and was diagnosed only a few days ago.
It is and will be a big change. Feel free to email me if you have any questions. You will have a roller coaster of emotions, well at least my daughter did and she she was only 9 when she was diagnosed. I can imagine that at 19, your life will be an emotional roller coaster for a little while. Remember the first year is the hardest, so we have found out.
