Not sure if this counts as SH or not
I grew up with incredibly abusive parents, both physically and emotionally, they just hated being responsible for us and hated being parents. They would also withhold money from us as kids and young adults.
They shipped me off to my native country for med school eventually. This country is a very savage place and I was not in my right mind after suppressing many years of abuse from them. I was finding it hard to live off of the small amount of money they were sending me, the people just wanted to use and abuse anyone naive, and the studies on top of all this were super tough. Living situation was horrible too, had a roommate who was spreading rumours about me and stealing my stuff.
Needless to say, I lost my mind. To try to improve my living situation I began living with my thief of a friend and her bf (at his apartment). Began engaging in hookup culture there, although all it was doing to me was making my situation worse, both physically and mentally. Does this count as self harm? I don’t want to go into too much detail but essentially I was just hurting my body, for many years and willingly.
