What the hell is wrong with people nowadays

Well, i rejected atleast 3 persons, The first one was a girl well, i could say she was a tomboy.. she was pretty tho. but there was one day she was shy and she gave me a hamster and confessed to me in the garden in school but huhu i was young back then i didn't know GL stuff, and now im still thinking about how that girl is doing, i rejected her harshly... gosh.... if i think about it im a scumbag...... and the second one was a boy he was tall, handsome, and the popular one in our school, but i heard he was a playboy i rejected him Lamao, now that i think about it he was my childhood friend in elementary, i thought, he was oddly familiar so that's why..., The third one was a disgusting guy , i hate him, in elem i was really ugly, when i was being bullied like people laughing behind my back, and when i cried hearing harsh words they took a pic with me and laughed, he absolutely did nothing and also laughed, but now in high school i changed completely my face and my outfit, he said he liked me, like bruh, are you kidding?, i wanna say f*** ***, disgusting creatures making fun of me for being ugly and now i changed they liked me all of a sudden, disgusting.. and now how should i say this.. is this what you call a "picky person", well, there's not a single person that's like in the manhwa that is perfect inside and outside, I'd probably just stay single the rest of my life
