Am I a bad person? what should I do?

SO that's complicated . I'm not showing off or anything but when I like a guy , he just likes me too?? I mean I like that , I love being liked and everything , but I just hate It when someone fall in love with me. Idk man , It makes me so uncomfortable, and I'm so sorry but sometimes I just wanna throw up. It's weird af.
I've been like that since my childhood ( you know when you like that cute boy next to you , so you give him a pen lol ).
I mean when someone confess I just wanna disappear. I hate hurting ppl and I hate myself for doing it.
I mean is that normal? Am I able to fall in love or smth or be in a freaking relationship??
