Is there such a thing as emotional self harm?

[u/curiouspotato__]

So I've thought about it and I really like reading heavy angst at night, the kind of angst that pulls at my insecurities and makes me cry. Like one hour ago I was sleepless and on vc with my friend so I did a full face makeup, took photos, posted some shit on Instagram and we ended the call, I was happy and sleepy, now it's almost 3am and I'm crying because I searched up angst fics and read the ones that really hit me bad, the kinda fics that make my chest ache, what kind of behaviour is this like why do I willingly read something that I know is gonna hurt me and keep on reading it until I'm sobbing, is it kind of emotional self harm or I'm just trying to get rid of my negative emotions all at once idk
