Help me from demoting to Bronze

Okay so I’ve been playing a lot lately like 3-6 games a day maybe during the week and weekend and I’ve been losing a lot. I’m a very competitive person and I like winning but the struggle with me right now is finding a role and sticking with it. I’ve been doing decent with master yi and hecarim but I dont find interest with playing them anymore. Last year I mained elise and it was fun but this year the game to me has felt like a up and down battle. I usually play Jungle which im pretty good at in my opinion though I have some of those moments of just playing bad. I just want a duo to play with or just to further better myself. Also when I play hecarim I dont do predator because I just don’t find the appeal to one and done, I like team fights and getting fed, jax is just not my gameplay style, eve i just never was fond of playing her, zac I don’t know what to think of him at this moment, nidalee is just god awful for me because I just dont play good with her. Im just having problems with finding a specific champ and sticking to him or her. Also i hate warwick. I just want someone whos fun and gets team fights going but doesnt throw the game in doing so. Shaco is my on and off main and so is hecarim but like idk if i should rotate between yi shaco or hecarim. Pls help

Edit: I was gold in june like gold 2-3 but I just started to play poorer and just didn’t listen to my teammates and thanks for the info guys
