i don’t know how to feel.

have any of you guys ever felt as if there is something about you that constantly repulses people. like i am bi 19M and i have never had a proper relationship, its always been one sided and kinda weird limerence. it’s not that everyone isn’t attracted by me, its just that those who like me are not liked by me and the ones i like don’t even acknowledge my presence. am i imposing self pity?
