I get this exact type of migraine for about 30 years. They are absolutely terrifying. For me it's more white lights and light sensitivity and a very dull headache. I've learned that if you feel one coming on, the best thing to do is get into a darkroom, put a washcloth over your eyes, get a glass of water to sip, and just turn some TV on very quietly. If you can nap, that usually go away a lot quicker than if you stay awake.

You definitely cannot just push your way through them. Don't drive, don't try to go back to a normal day. If you do that they will last a lot longer. I'm really sorry you went through that. I know how terrifying they are.
