I use people in my life that I don't like.
Why do you use people that you don't like?
Because I don't like them and want to drive them away.
I know that you don't like these people but it's not right to take advantage of them and use them. If you really don't like them, you should tell them and distance yourself from them.
I just want to get them away from me.
I understand that.  The best way to do that, however, is not to be abusive towards them but instead to be direct and honest about your feelings.  Nothing says you need to like everybody!
