extremely bad luck?

ive been having rlly bad luck lately and idk what's wrong and its sending me into a spiral. like im talking abt failing every test even when I know the content, doing bad at my sport, my teachers being terrible to me, like literally every day is me waking up and expecting something bad to happen like it just gets worse every day. I don't know what to do anymore, im trying to try harder but that's not even working... like anything I plan gets canceled or goes wrong, I literally have a canker sore now??? when I was saving a file today right after playing a bad game and failing a test and an assignment my storage suddenly got full and I couldn't save the file to submit homework. Yesterday, I failed two tests which dropped my grade tremendously. I went from being an A and B student to being an all B student. I don't know if I'm doing something wrong, I'm trying not to be negative but when like everyday multiple things go wrong I just can't like force myself to be optimistic. Any tips to get out of this rut? I'm sick of everyday being a bad day. Like I genuinely think a piano will fall on top of me tomorrow... Like every day this week has been like one thing goes wrong in the morning and it just adds on from there, and it's even affecting my friends too. Like idk if my bad luck is contagious but like they will literally have the worst luck sometimes and it might because of me. I'm literally going to hire an Etsy witch or something. Please someone give me tips or at least relate to me to feel better...
