PMDD and anxiety/physical symptoms

I’ve been trying to keep track of patterns for the past year. I’m finding the week before my period, my body shuts down. And every cycle is different. The most constant symptoms are feeling weak, lower back pain, leg weakness/numbness, and increased anxiety. I feel terrible as a I type this but my gut tells me if I went to my doctor tomorrow, she would chuck it up to my cycle. Not only do I deal with anxiety disorder on any given day, but this just adds fuel to the fire. Like my brain is telling me I’m having a heart attack.. I’m 25 (I know one can happen at any age but just giving all the info I can)

Does anyone else experience these episodes? (In the best way, I hope so..) I feel crazy and alone.
