Help?!? i'm 15 and i think i might have junior fibermyalgia?!?

I'm 15 and have been having bad stiffness and pain in the top corner of my back on the left side, and starting to come a little on the opposite bottom corner.... it comes and goes but i really think there may be something wrong considering its in the same exact spot everytime. I also have a really hard time going to sleep (i have been taking sleeping pills but they don't seem to be working anymore) and its hard to me to wake up in the morning. I have told my parents my suspicions but they think i'm just being dramatic and wont take me to a doctor. please just tell me what might be going on, or if i should make my parents take me... we don't have insurance anymore, so i think thats why they wont take me.
