I'm glad you don't feel alone anymore!
I've been listening in on this group for a while, but never responded. I'm sure there are plenty more of us that just stay quiet like me, but you're definitely not alone. When I was in college (seems so long ago now), I had bad anxiety like you describe because of it. I was afraid of going anywhere in fear of getting one. But the older I got, the less I worried. I've been having these for 20 years, and I figure if they haven't killed me yet then it must not be something to worry about!
Just go about your normal life, don't stress about it, and if you do get a migraine in the middle of something important, you'll find that people are far more
understanding than you realize. I've come to be thankful for the SS, as it gives me a nice 30 minute warning or so that I'm going to get a migraine, so I have time to get myself to a dark quiet place (hopefully my bed).
Just hang in there, it gets easier!
