Noone likes to be disliked and it can be painful but you have to accept that not everyone is going to like you which is easier to do when you like who you are and are being true to yourself. By all means do take a look at yourself if you find that this is happening more often than it should and give yourself a reality check and if you believe that you may need to tweak a few things here and there to be able to remain true to yourself then so be it but don't change who you are just to try and please others to be liked. Instead accept the differences and be grateful that you are not a people pleaser who has compromised themselves to be liked and has to seek validation from others to feel happy about themselves!
