I’m really sorry. Just to offer a little hope, a friend of mine at church was beset with almost daily migraines when she hit retirement age, if you can believe that. Several years of trying everything, and a hail Mary pass trying amitriptyline of all things finally calmed them down. She still has mild symptoms when weather fronts roll through, but it’s much improved.
I really hope you find something that works well for you. Migraines suck.
