Lol, hell no. Worrying about stuff like that is pointless. No matter how nice you are, no matter how giving you are, there will always be someone who doesn't like you. It's a very normal thing and I'm OK with it. I'm pretty sure everyone has come across someone they didn't like for no reason. Also, worrying about stuff like that only damages your inner peace. It makes you doubt yourself and what you do. Just because someone hates you, doesn't mean you did something wrong. If they don't wanna get to know you, that's their choice and all you can do is accept that.
