I'm going to kick people out of my life out of nowhere
Is there a reason to remove these people from your life?
I don't have to tell people why. They're just going to know it
It is okay that you do not want to be around certain people and have your reasons for it. But you should not kick out people from your life who are close you you. You should be loyal to them.
All friendships have a time limit.
That is not true, some people are going to be friends forever. I think that you should remain loyal to those that you are closest to.
