You can do it. Bronze has some of the silliest games I've seen. If you want, you can duo queue with me sometime; username Tgump. Play someone who can carry lategame with lots of farm in your role. For example, as I'm most proficient at AD carries, I like Tristana or Vayne for lategame damage, but Vayne has pretty complicated mechanics, so I wouldn't recommend trying her for the first time in ranked.
Edit: Looks like you're EUW, so we can't play together, but I guarantee you that ANYONE (if they deserve to get out) can get out of Bronze. I got placed in Silver 2 after winning 6/10 of my promotion games and I went on an 11 game win streak.
