Hey don’t beat ur self up for it ok, i used to be like that all the time. But u gotta apologize first and stop and think about how ur talking to someone. And its just how life works ok mistakes are made, they might treat u poorly but they still love u ok?

Could be some subconscious thing. Perhaps you’re repressing your emotions or some sort of problem. Is something worrying you? Something made you mad? Sit for a moment and think about your life in the now.

Are you an angry person? Maybe that has something to do with it

It takes practice but try finding ways to speak kindly to people. It will make you happier inside too

Sounds like your a young teenager, it will pass and try harder with every one with how you speak to them and sometimes just dont say anything for now

Self introspection and regular Meditation will help.

Best Wishes :)

I've been there. Probably just built up anger
