Went Through A Couple Years Of Trauma, Now I'm Always Looking For A Fight
In the last four years I've experienced some intense trauma. I'm in my 30's and had until recently lived a life sheltered and badly influenced by a toxic family. My sibling is a diagnoses narcissist who would regularly emotionally abuse me and forced us all to focus on her at the expense of my own life. My mother I'm fairly certain has serious mental health issues, she is in her 80's put acts like a child, she never let me do much myself and as a whole they taught me a lot that isn't the way actual people or society operate.
This all came to a head when a well meaning woman I got into a relationship with invited me to live with her and I moved in, we'd only known each other for a few months, so moving in that early was already a bad idea, but now I was away from my family, all the years of terrible parenting, a warped world view and terrible parts of my personality that had been excused when they shouldn't and I'd been taught they weren't bad came to out, and she had to endure it all. Our relationship crumbled, I was kicked back to my parents after 3 odd years of stress, guilt and hard realizations. Along the way I lost a boyfriend of over 10 years who I loved with all my heart. Losing him shook me to my core, to the point even seeing a picture of him is liable to give me a panic attack. (I'm polyamorous, and looking back, I'm not even sure me and my other partner would've even worked out in the long run)
I managed to move out on my own to a small flat a little over a year ago. And since the entire incident with my ex girlfriend I've noticed I've become a much angrier individual. I'll go into comment sections on youtube, reddit or steam discussions specifically looking for those who post bigoted, hateful comments or just act in a way I deem "bad" to fight with. Sometimes I've looked in the comment sections of random websites and made an account purely to post a reply. Sometimes these replies can get very spiteful and intense. Wishing physical harm, disease or grief on them, sometimes at my hand. All delivered with a gleeful relish.
At once point I was forced to go cold turkey on SSRI's and found I got a rush from watching action scenes in movies where villains would be physically harmed in graphic ways. This worried me, I wondered if I was a psychopath.
Now it's extended to friend groups. I've started snapping or giving sarcastic quips to people at gatherings who might do something that irks me that is either not their fault or just a result of disorders or lack of social skills, such as making the same harmless joke a couple times or making noise when people are trying to listen to something. I don't like any of this. I worry what it means of me as a person, I used to be a pretty gentle person.
For context: I've been diagnosed with Borderline Personality, Autism, ADD and OCD, if that means anything for any of this.
How the hell do I work this out and stop myself turning into a monster?
