am i the only person who think i’m the exception in regards to my ocd theme. like out of everyone i’m going to be the person who ends up being my biggest fear

I went out with my partner today to spend the day together and try and do some ERP. the whole time I linked my arm and had my phone in my other hand. I would purposely move out the way for children or notify her so she could see I didn’t do anything. Please tell me I’m not the only one with this type of harm OCD. I’m really panicking and it’s making me feel sick. I had that feeling where my stomach drops and I’m scared of my thoughts

it started when i simply worried about my partner losing feelings because she was being a bit distant and so i obviously spiraled and started thinking “oh yeah she has to be losing feelings of some sort” she was only being distant because she was preparing for her confirmation party (this is important) and me and my friend hung out the same day and ended up walking to her house to say hello to her as a joke. but i was already way too deep in my spiral. right after that interaction with her, she literally reassured me right then and there that i was “cute” and that “she really likes me” but i was so caught up in the idea that shes losing feelings for me that i couldnt accept the reassurance and kept having intrusive thoughts that shes lying to me and that she doesnt mean it. but whatever, i wasnt THAT worried because her confirmation is coming up and she wouldnt lose feelings for me before something like that right? a couple days pass by and im at her confirmation party, shes being a little distant but only because shes tired (evidently too) and so i was still in a spiral. but then i met her family, and her mom let me have her number (in case i wanna schedule something with my gf) and that sparked a whole episode. i talked to her mom a couple times and started worrying about if what it would be like it i left my gf and how it would affect me and her family and quickly a thought followed up with all her physical imperfections and how much i dont like specific ones. and then another one came up. i saw one photo pf my partner and swore it looked like someone in my math class who isnt attractive. i managed to get rid of that thought the first time, and had to deal with the imperfections idea thing for a whole month. recently tho, the unattractive girl from my math class is popping up in my head again. i cannot get it out of my head, any advice? what is this phenomenon and also im pretty sure im the only person who has dealt with all of these thoughts.

I feel like every person I see who has recovered from OCD doesn't have my theme. I feel like I woke up in a nightmare I can't escape and it'll never end. Do people actually get better from this?
