I don't know what it is, but when I have moderate to bad one, my cats flank me and purr up a storm. They don't usually do that. I am surrounded by kitties. Thanks babies.
ETA: What is it about migraines that make me an emotional wreck? I almost lost my shit on the phone with grubhub because the restaurant didn't deliver my smoothie with my order and I was all "I HAVE MIGRAINE AND I NEED A COLD SMOOTHIE BECAUSE PAIN! I DON'T CARE IF IT TAKES ANOTHER HOUR. I NEED IT!" Then I started crying at the "emotional" end of a stupid show I never watch. Then I started crying because my life sucks and it's never going to get better. I want to to sleep for the next 12 hours.
