I don't know why I hated her and I hate myself for it.
Can you think of any reason at all that you would hate her?
No, I don't have any reason. I think I just hate everyone.
It is not good to feel as though you hate everyone. You will become angry and unhappy all the time if you have that mindset. Talking to someone about your feelings can help you work through why you dislike people so much.
I don't think I can help it. I just don't like most people.
I believe that you should look a little harder into yourself, and there has to be a reason why you feel this way. People around you would enjoy you more if you found out and figured out how to work on it. No one deserves hate, even you.
