Forget those who forget you

I think I am getting used to the fact that everyone is temporary and all i can do is NOTHING. Sometimes we get sad about things and we don't like to tell people that we are sad about them. Or sometimes, we are sad but we really don't know why are we sad, so we say we aren't sad but we really are. Maybe we will really never get over some people but it just makes us think we've already moved on. The things about thoughts is that they can make you feel alive and also kill you inside.
