Bronze (almost Silver ;_;) looking for Diamond Jg Main

I play top right now, but my favorite role is jungle. I'm currently stuck around 30 lp Bronze 1,winning one and losing one. I would like someone to help me learn how to not feed,and to make the right decisions to impact the game in a good way for my team and I every game. Currently I play top, and occasionally jg in norms, and die way too much and never know what to do with myself. Help me pls T.T
