RIOT I NEED ANSWERS

In my last 20 games id say 16/20 are affected by this. You may wonder what "this" is. Well.

AFK: I have afk a lot on my team. Feeders: im always on the team with feeders. I went 2/0 in the first ten minutes as Lucian and my annie went 0/6 and top went 0/6. I feel like my team always feeds and im playing with level 10s. Speaking of level tens I played about 7 ranked games I think. I have lsi which tells me everyone rank and we have a team of bronze 5s and I was bronze 2. and the enemy ha 3 golds. I feel like this always happens

RITO CAN YOU TELL ME WHY 16/20 ARE AFFECTED BY THIS AND I LOSE BECAUSE OF IT.
