I finally understand what "ELO Hell" means

I have a friend I tried to queue with a few times when they were on, and one that we were on a win streak with together, so we could do ranked because Bronze players are super toxic and where "I'm the best player" goggles. Backstory, done.

Yea, the second I solo Q into bronze ranks I lose. 2 times. In my series. I'm not sure if its my fault or not, but I need help with understanding one simple concept. HOW THE HECK DO YOU CARRY A TEAM THAT FEEDS?!!??! Seriously, I die once or twice in lane tops or I shut someone down (my Teemo V nasus game, in which someone said Teemo was a really stupid pick.....) entirely. But, my team feeds elsewhere super duper hard. By the time we make it to teamfights, not only can I not do anything- but when I see a REALLY good engage "Yo guys, ez ace. letsa go"...and no one follows. When they say, no they're gonna loop and kill...and meanwhile Nasus is farming top, Irelia and Reksai are bot, the other 2 are mid, 4 of us are mid, and only 1 of us dead. How is that not a good engage? We had the two squish carries against us.....=( #rant done

tl;dr: How do you carry a team that feeds so hard that by the time you get to team fighting, the other team is like 23 kills higher than your team? This isn't accusation, I just wanna play in a better rank where I don't have to go from 0/1/0 (where I go from fighting, to solely farming to keep on track with my opposing laner(s) and hide how much damage I do to them) or 3/1/1 to 2/9/3 or 3/7/5.
