I know how you feel and your not crazy trust me, when I first started having my migraines with vertigo I thought I was having a nervous breakdown. they went away for 2 yrs and then 1 1/2 years ago they came back with a vengeance then never went away, I had tunnel vision, double vision, throwing up, the works!
I too tried all the classic meds Imatrex, Topomax, topomax made me feel worse! toradol, all the beta blockers, pain meds, muscle relaxers, then had countless MRIs, CAT scans, it has been a horrible life.
I then moved to Kansas and saw a migraine specialist in KC and had Botox injections about 8 days ago, and has worked wonders for me the headaches are about 85% gone!
I went through hell and back, and hopefully the Botox keeps them at bay, then after the Botox they are going to do a permanent migraine surgery.
Have you tried Botox, or a neurologist?
Keep me posted, Im with ya!
