Sorry to hear you are suffering so much! I certainly hope that the migraine is much better, if not gone, by now!!
I was getting severe migraines daily for months and months and months. Finally, a few years ago, was able to get in for treatment at a headache clinic. We have figured out a combination of preventative meds, botox injections, lifestyle changes, and rescue meds that have cut the # of migraines down from 30 a month to an average of 2-3 (much less severe) migraines a month. Obviously everyone is different, and what works for one person may not work for another, but maybe you need to explore some other/new options in your treatment.
I don't know much about your migraines, how often you get them, or how they affect you, but if you would like to "talk" more, I'd be happy to share my story, help any way I can, or just listen if you want to vent. I know how frustrating it can be, and how it really robs you of your life. It sounds like you do have a good neurologist, which is awesome! When you have the energy, be sure to keep pushing and searching for a better answer to the problem. Don't settle for just "getting by". You've got a life to get back to living.
Let me know if I can be of any help!
Good luck and take care!!
