So like (TW: Period (Transmasc btw, no this is not a depressing vent))

Usually it's said that when AFAB people get their periods, they're more angsty and irritable. However... while that DID happen to me this afternoon, something else also happened. I was... weirdly optimistic. I sent one of my friends some sorta "Reasons-why-people-care-about-you-and-how-I-know" list. (Man I am cheesy!) I was suddenly super damn happy! Which is good, but why? Does anyone have any answers?

Update: Calmed down after sending more motivational messages!!
