New Player in need of training

Hi, I've been playing lol for a little over a month now. I play almost everyday for a couple of hours. Sometimes more, sometimes less. Anyway, I am finding it very difficult to even get somewhat good at the game. I was hoping that a team could pick me up temporarily and help me improve and learn the more advanced stuff. For example, when I play, I don't really take a role. I just play. I don't have a good understanding of how to play each role effectively. I really need training or help to improve my game.

Recently I've been using Fiora (ADC I suppose) but I don't plan on maining with her. Still I can hold my own most of the time. My backup fighter is Garen and I can kinda support with Soraka. Like I said, I'm new and only have these three champs. But I need others help for many things. I need help picking a better champion, playing roles properly, and so on. Who knows, maybe I'll get really good and become a really good player for the team. But in the end I just really need some training. If anyone reads this and is interested in helping me, let me know! My summoner name is JameX Strickland. I live in the USA and play a little after 2 EST and after 8 EST
