Whats wrong with me?

So recently i have just been losing so much and i dont know why, ive been a consistent diamond 5/4 player since s7 even in s9 i had no problem staying in diamond with ex master lobbies and i havent had any problems stat wise. This season ive played around 60 games and when it started i was doing good but around 4 days ago i just went in a huge loss streak and i havent been able to get out of it. Went all the way to plat 3 almost 4 and i have been trying my ass off and still managing to lose. I take breaks because im studying for finals but even with breaks i cant seem to start climbing back Should i just take some days off? Any advice would help

I can provide a match code if anyone wants to see my gameplay
