Walking is magic (and low-key works better than therapy)
I have PMMD (plus a lot of legitimate worries over health issues). Got out of the house at 3am because I couldn't cope anymore. 20km and 30k steps kicked the bad thoughts in the ass and left me full of energy even while I'm on my period.
Legs and feet are slightly sore, but I feel so good. Like, genuinely at peace.
