Difficult day

Idk about a lot of people on this app, but it seems like I get stressed out from people almost every day. Starting with my stepmom not likening me, which irritates me, because then I get no time with my dad to hang out with him. Then when he notices I have issues with her, he takes her side and I am nothing to him at that moment. It makes me super angry and i just get in a bad mood with everybody. Then their is my brother who tells me that I am hogging all the WiFi by watching Netflix, so then he threatens to throw my phone out the window, and sometimes he says that he wants me to kill myself, or that he is gonna kill me, which I honestly shouldn’t take personally since it happens almost Dailey, but at the same time, I don’t think I have ever heard him say I love you, and my mom says it’s just because we’re both teenagers, and we both think the other is stupid, but I take him seriously when he says this stuff, and it hurts my feelings. Also, I have younger siblings, and they like to follow me around and do my every move. They copy everything that I do, and sometimes it is cute, but sometimes I am in a bad mood and just want to be left alone with my dog of course😂!! And finally, myself. Some days I just wake up and I am just naturally angry or cranky. It could be because I stayed up to late and then had to get up early or other reasons, but I always feel like their is a reason that I am stressed out and angry. Plus my only way to get rid of this stress is talk to my friends, and idk if that is healthy, because sometimes we could be talking on a subject for a couple hours and I want to forget about it. Anyways. If anybody can relate please tell me down below. ⬇️⬇️⬇️
