If that person hated you and you don’t don’t the reason, if you had asked her but gave no reason, I would say, IGNORE her, one day she will be curious and ask you instead.
People are weird, the more you try, the more they ignore, might as well ignore your haters, who knows miracle might happen

I feel bad about a friend suffering from this problem as I have been through a lot of situations like this, I know exactly how you feel, but let me tell you, it will disappear.With a pure heart and true concern, it will disappear one day. They will realized what they had done to you and you are not there anymore for them to see it happens. I don’t know how to console you, but I am your friend, I will do my best to make you feel okay. It will be okay. Let me pray for you and for them as well. It will be okay on the right time.

thanks dear @grecy and peachpurple for your healing words.

Though you may not be a celebrity, that has nothing to do with why people choose to dislike or even hate you. Just don’t reciprocate the feelings. It will only hurt you. My late mother taught me this. Don’t bear a grudge. Don’t be jealous. Don’t envy. Don’t hate. Don’t render evil for evil. Because in the end you lose. If you rise above this, one day you may be able to lift that hater out of the dark hole they dug for themselves. Believe me. Hating hurts the hater more than it hurts you.

Honestly I don’t think there is anyone who does not have haters in this world, not everyone can be your friends, not everyone is happy with you or with what you do, and funny enough we need them in our lives to be able to know how to handle conflicts and stuff like that. As much as it may sound ridiculous to accept haters in our lives it’s necessary. I know I also have haters in my life people who look at you and think, your not worth having some things or your not worth being somewhere at a certain time. Such people are meant to strengthen us not destroy us. I remember sometime back a friend of mine was interested in some guy and she was doing all sorts of things just to please him so that she would go out with him, but fortunately or unfortunately the guy was not interested and decided to pick me and took me out and that did not go down well with my friend, so she started trashing the guy and saying all sorts of bad things about him so that I wouldn’t consider going out with her too bad.
