please tell me i’m not insane but does anyone else w/ a uterus get super fucking triggered like before and during their cycle

i have been in recovery and symptom free for months and doing SUPER well, but for some reason today i was freaking out and super triggered. crying for the first time in weeks, the smallest things set me off like my dad not offering me food when i told him i was hungry or etc

then i realized when i started having an upset stomach…….. i was about due to start my period. so, i check my flo app and low and behold, tomorrow is my period!

i feel crazy, is this real?? i was always told growing up that the hormonal emotions thing was a whole sham, but now it’s like…. ehhhh
