migraine hell

Hi there. my name is Rachel i'm 20 years old. i have suffered with migraines from the age of 7. i have had every single medication to treat my migraines. the severity of them has become debilitating for me. It has affected me socially and in a work environment. In nov 2013 i had to leave my job as i was constantly being sent home, the kind of work i was doing was very stressful so i needed to take myself out of that situation.

The things that tend to set them off are sunlight, heat, stress, worry, eating a lot of sweets/chocolate. I am so desperate at the moment. i get them constantly, i have seen a migraine specialist and he did nothing for me other than prescribe me with propranolol. I currently take pizotifen for them which seem to help me a bit, well more than any other has, although i have put 3 stone on in 2 months with it. The whole situation has caused me to relapse; going back to my extreme depressed state.

i was wondering if anyone would be able to give me some advice on what i can do about it, as GP's don't seem to know much about it.
If anyone knows any alternative methods on how to get rid of migraines when an attack occurs or a non medical method. i have tried all medication so i am at a loss. I get them at least 3 times a month and they last from a day to a week :( i once had them everyday for 3 months constantly!
