After exhausting five-second research on google, I'm more confident to say that it's all normal to cry in the shower, and it saves time.
βAccording to Metro, a new survey says that 74% of people admit to do most of their crying in the shower, and most people admit they do it there because there is privacy and because the water can drown out your sobs."
Especially running late to a cuddle session, and out of respect, I asked the cuddler to start cuddling without me. I've had great sob sessions in the shower after getting home.
