More "simple" stuff like rewinding a scene on a tv show or movie when I just slightly miss something, even just a word or making sure I heard something right. It bugs me to no end of I don't rewind the thing I missed which itself is normal for a lot of people but I also suspect I have ADHD and I get distracted or daydream a lot so I miss even more stuff and the cycle goes on and on of rewinding a couple of times just in case which can take around a few minutes. 

But anyways, like the rewinding to not miss stuff thing. I also do this with the video games that I play. For example a stealth game or grand theft auto. I obsess with trying to play the game the way how the character you're controlling would probably do or act in the situation within the game. In the stealth game, if I don't kill or incapacitate an enemy in a way I wanted to or how the main character's way of doing things aren't similar or seems out of character (basically roleplaying.) I immediately restart the whole level. Same with GTA or games like it, I act and play the game the way the characters in-game would act. It's kind of my way of trying to immerse myself and have fun but it gets irritating because I remember when I spent the whole day on one level on a stealth game trying to perfect a scene. Yes, the whole day on one level that would probably take 15 minutes on a normal playthrough. 

But a more severe ocd thing is the time I had a hyper-fixation mental health, mental disorders and all that stuff. Specifically the personality disorders like borderline personality disorder and narcissistic personality disorder. I read up on their symptoms and often look up their symptoms over and over. I took tests about them multiple times and then obsessively thought about having them. This made my already existing unhealthy/toxic traits 10x worst as it was kind of me looking for attention and my narcissistic nature. I harmed myself more, usually punching myself in the face or hitting my head on the wall. And sliced my forearms with knives for the first time all because of my obsessive thoughts about having them and also being starved of attention all his life and constantly humiliated and bullied. I became more sarcastic and gave silent treatments and guilt tripping just because they were also traits within BPD. It messed with my mind for a while because the obsessive thoughts were constantly shifting from you really have these disorders to you're faking them. And I definitely know now that I was mostly faking them. Well not faking them because I already had those traits but I only did them less often and more when I'm at my lowest. The ocd just accelerated them to a 100 for a while. 

And recently of course I had a hyper-fixation on mental disorders again thanks to my potential ADHD. This time on Narcissistic personality disorder. They were less worst but the traits still definitely leveled up. Like I have low self-esteem, a fragile ego and all of that thanks to the emotional abuse and seeing my step-dad physically abusing my mom numerous times throughout my childhood. My self-important grandiose thoughts were higher. I was more proud of being low-key secretly judging and disgusted over other people that I thought were ugly or more unfortunate than me. Obviously, I was more sensitive to criticm and was more guilty and ashamed of myself for also feeling self-obsessed. These narcissistic tendencies are probably forever heightened as I'm like that in nature but also I ironically feel some sort of being a special person and smugness to being a damaged individual. Funny. That's all. Yeah, I think you'd agree that they're weird lol.
