Helpless

My 17 year old daughter has suffered migraines since she was 12.  Each year they get worse.  She is currently in grade 12 and has missed so much school she won't be able to graduate with her class.  She has been off school for almost 3 months with recurring migraines.  She wakes up every morning with a migraine.  She has been taking propanolol, amerge and fiorinal.  She has been to the ER twice in the past couple months where they put her on IV.  At the first ER visit the Dr said she had developed a dependency to the fiorinal and it was causing rebound headaches.  We got her weaned off of that but the headaches keep coming back.  She has also had 3 demerol shots at her dr's office in the past month and the dr is cautioning us that she could develop a dependency on that too.  She has an appointment tomorrow with a Naturopath as we are desperate to find some solutions.  She also has an appointment with a Neurologist in two months.  It is devastating to see this beautiful, bright girl going through something so horrible.  She can't live a normal teenage life and her troubles keeping up with the school work are preventing her from reaching her potential.  She wants to go to college and I worry how in the world she will keep up with migraines consuming her life. If anyone has some advice of what we can do please let me know.
