I unintentionally insult and hurt people and how do I stop it because it's pushing all my friends away from me?

Does it bring you some kind of happiness hurting people like that? How would uou feel having someone treat you the way you treat others. Something to think about. Don,t just think about what you say before you say it. See the results before you insult someone and the hurt it,s going to cause. And understand why everyone has left you. Only you can change this about you. Life can get pretty lonely with no one who cares.
