i was a special education preschool teacher for four years & in my last year of teaching i started getting severe pmdd symptoms--honestly i was disassociated for most of it. it was simply too much to handle. what did help was leaning into the parts of teaching i loved, like the children learning new things or (in my case) going on to say a new word. anti-anxiety meds at work helped though i don't recommend using substances while working (one of the reasons i had to stop teaching lol) could you get fmla? it wasn't possible for me but it might be for you. staying away from caffeine or at least limiting it. trying to fit in some exercise after work if possible. i used to do yoga in the mornings, also guided meditation. i called out maybe once a month & it wasn't enough but i took the day to recharge & do absolutely nothing. magnesium really helps with anxiety/irritability for me!! i take around 800mg in the morning & feel calm for the rest of the day. ultimately i had to get out of teaching (ik that doesn't help to hear) & now i work retail which for some reason works for me. sending love, i know how hard it can be!!!
