I'm scared to open the curtains now

I never get headaches but have now been diagnosed with gastric migraines caused by my oestrogen going too high which puts too much fluid in the cells and overstimulates everything.
I also lost appetite (and stones) and felt as if I was plugged into a socket with everything pulsating here there and everywhere. I'd never even considered migraines even though I had a constant tight congested feeling in my head. I may still be getting blood tested for pituitary problems if they think necessary once they know if progesterone was enough to take the water out of the cells.
I'm assuming mine is rare but maybe all these meno neuro and motion sickness issues are migraine/pituitary based?
