I am having much trouble right now because seemingly almost every time I open my mouth and say something, I seem to hurt someone, especially the ones close to me. I don't mean to; it just happens. I've hurt my mum, sister, best friend, I even hurt my ex-girlfriend when we were still together. I don't know what to do any more, and if I hurt anyone else, I'm just going to break down. I can't take it. I never mean to hurt anyone, it just happens. What can I do?
