Change my attitude

I gfind a i have a really bad attitude problem. Someone will say something to me and without me even thinking about it i answer back rudely and try top shut them down. When i actually think about it there is the nicest tghings i could have said back. But instead i go off and do and say what I wanna do. I need to start thinking about other poeple aswell. I don’t like fighting with my mum and brother and i find when the fights nearly finished that i tke it that step further and it gets really offensive. i just want to stop being so rude. Sometimes i say things and most of the tuime i don’t mean it. Ive made close relatives cry because of what i have said. I need to change this because i feel so bad of what ive done.
