Hi Jordan. I found your question about there being anyone who is 19 with fibromyalgia while googling "fibromyalgia at 19". I was googling this because I am 19 and was diagnosed today. I am a preschool teacher and it's my dream job but i am in constant pain. The onset of the fibromyalgia we believe was brought on because I was in a mentally and emotionally abusive relationship with my highschool sweetheart and I was under severe stress. I haven't done much research about fibromyalgia because I didn't think I had it but I do... So you're not alone. I also have two more friends with Fibromyalgia who are both 18. They've had the diagnosis for awhile though.
