Hi Akalie,
Great question! Migraine disease stigma is very real and this article discusses it in great detail; http://practicalneurology.com/2018/02/the-stigma-of-migraine/.
Anticipatory stress, I'm not sure if that is an official name for a type of stress but can be very real, is when we anticipate a migraine attack will occur and dwell on it. That in turn may possibly trigger a migraine attack. Dr. Silberstein discussed this last year at one of the migraine and headache disease scientific conferences I was able to attend last year.
I'm sure others will be along to share their experiences with you.
