As someone who has a had a chronic illness since 12 these are all so true. Not only do doctors not listen your parents may not listen to you too. I grew up thinking that I was wimp because I struggled so much with all my symptoms. I also that I was crazy. Once my parents finally took me seriously the specialists I went to told me it was all in my head and that I needed to see a psychologist. That's hard for anyone at any age, but especially as a kid who is trying to find their voice, they take a huge hit.
