Rainbow,
I also deal with chronic migraine. It’s hardly fair. There’s a book called The Migraine Brain that is very useful. Very practical and grounded in science, merging modern medicine with complimentary medicine. https://www.amazon.com/Migraine-Brain-Breakthrough-Headaches-Better/dp/1439150354
I have also been diagnosed with PTSD, GAD, and MDD. So yeah, I get it but, I found that a blend of modern and spiritual approaches work best. Together they are stronger than apart. Anyway, I hope you find relief soon.
Oh, and before I forget, you may find this helpful too. https://americanmigrainefoundation.org/
