In this life, it is a common if you find one or two or more persons do not like you. It can because your personality or something in you that does not fit them.
If you are in this situation, you should not overthink about this. You just need to evaluate and realize your fault. If you have made mistake so that they hate you, you should ask for apologize. Talk to each of them personally, who knows there are some misunderstanding among you.
But if you feel like you do not do anything and there are some people do not like you, you just need to obey them. You should not change yourself just to make them love you and accept you. Officially, you should know that you can not please everyone.
If one, two or some people do not like you, it doesn't mean you are antisocial. It doesn't mean you can't socializing so that you are not accepted. It is sometime because their own personalities, like envious or jealous. Just let them go.
Keep being positive person and spread love and piece. Treat everyone well and if there are someone or more hate you, just act like you do not know about it. As long as you never hurt other people, it is not your bussiness whether they like you or not.
Never reply other's bad attitude with the same bad. Just make some distance with them. It is okay and recommended to stay away from toxic people. It is the best choice just to keep you save from negativity.
Do not let others make you down just because something you never made. Do not ever think that you should be hated because you feel that you are antisocial. Once again, it is not your responsible to make everyone like you and happy with you.
Nobody is perfect. And nobody can force you to be perfect.
