Stress

Sorry for my language but I'm extemely mad right now. My fucking brother and sister stress me out so much. I just want to hurt them and throw things around. No I don't have anger issues but they stress me out so much and assume things that it makes me angry and yell. I need things to cope with stress. No, I'm not buying anything for it, I'm not going to therapy. I just want at home things to relieve it a little. And no I cannot just ignore them. I just want to know any tricks or things that yall use to help cope with it. I've finally lost it. Thank you
