My Awful Match History

Kill Me. Now. I have just finished my 8th game in an 8 game losing streak (besides one game of ARAM). Honestly, I don't think I play that bad. I know that I make bad decisions sometimes, but really am feeling pretty defeated atm. If you look at my match history, you can see that in my most recent games, I have played quite well. Every game I try to play a champion that can really help my team, because I am a team player as much as the next guy but am about at the point of just being toxic and farming all game. I out-farm anyone in the game, while also getting very many kills while also focusing as much objectives as I can. During the game I played today as Kha'Zix, I went 15/6/6, secured multiple dragons, attempted to contest as many objectives as I could, and we still lost.

Having just been placed into Bronze 5 with no LP, I'm at a loss as of what to do next. I constantly watch my own replays, streamers, and LCS to try and learn as much as I can about the game and ways to play, but don't really understand why my loss rate is so high. I don't tilt easy, stay fairly calm in games, and do my best not to be crazy, but just get nowhere. Is this a common occurrence for someone who is only 2 years into the game? Id really love any help I can get because this is just unbelievably sad.

Also, are there any speedy ways you know of to get out of bronze? Any would be great. Thanks a bunch,
