It feels like nothing makes me change my mind

I am incredibly insecure over the fact that throughout my entire life not a single person has ever had any romantic feelings towards me. It makes me feel insecure, unlovable, and repulsive. But whenever I reach out to anyone to anyone and express to them, the response is predictable and never makes me feel better. Its always something along the lines of “you’re young, you have so much life ahead of you” or “you don’t really know if no one has had a crush on you.” I find those responses both unhelpful because it doesn’t change that for many other people at least around me, they have experienced such. If I’m the only one around me who feels this way, it makes sense that I am the outlier so something must be wrong with me. But I am so tired of being lonely and I don’t know what to change about myself to be more worthy of romantic attraction.
