uncomfortable when someone crushes on me?

i’m putting a TW just in case anyone is having a similar issue to me—i’m having a mixed battle of SOOCD and ROCD and i am looking for some advice. does anyone else feel this way? i have for as long as i can remember. whenever i find out someone has a crush on me and tries to execute their feelings towards me, i instantly get a pit in my chest and i want to avoid them as much as possible. usually if i find out they have a crush on me i’m like “okay whatever that’s fine”, but the moment they try to do something about it is when i feel as though i’m being suffocated. i think a lot of it has to do with the fact that A. i’m hyper independent and usually prefer to be on my own, B. i recently discovered i have an avoidant attachment style, and i have never been an affectionate person really at all, whether it be with family or friends. and C. most of the time, i barely know the people who crush on me and i get uncomfortable at the idea of someone thinking about or perceiving me in a way that is not reciprocated. it feels like a bunch of eyes are on me, and being independent and shy i hate that. i’ve only had about 5 real crushes in my life and i don’t think i’ve ever actually been in love—i think part of that is because i don’t really let myself form relationships often. i’ve always chalked it up to me being independent and shy and telling myself it will change one day and that it’ll happen if/when it happens, but i’m worried it won’t. i’ve never been the type to actively seek out relationships, just let time do its thing, which i usually would be doing right now but ocd decided to swing onto this vine like tarzan. i try to give myself slack because i’m only 18 and i have so much life ahead of me HAHA but who knows. weirdly enough i’m kind of a hopeless romantic because i love to daydream and fantasize about finding love, i love romantic situations and i often have dreams about finding someone, but then when it actually happens my body goes into self protection mode and i self sabotage in the end. worst part is once it’s all over i’ll feel like an idiot that blew a chance, and then the cycle repeats. i’m meeting with my therapist soon so i can hopefully resolve this because i miss how my life was before ocd started attacking this hahah anyone else this way and have any possible tips for me? thanks (:
