Bronze 1

I am a Bronze 1 trying to claw my way out of Bronze, but I have the mmr of a Bronze 3 player. Troll teams, feeders, or shit like that and it's pushing me beyond my limits. I'm going Nasus top but the other lanes are either feeding, or just complete trash. My mmr is tanking because of this and It's awful. I feel like quitting LoL all together, and I know alot of posts like this have already been made, but any response would be helpful.
