A simple request

Hello. Thank you for looking at my post. Last season I was able to reach a peak elo of silver II, This season I have fallen to bronze II. I have tried a variety of champions and practiced a ton but am unable to get back to where I was. I have asked a couple of high elo players about what to do and they have given me general feedback. They say "practice more," and "look at better players," and the usual stuff like that. I have taken an effort to do what other have told me to do, and put in the time, but I am just unable to get back to where I was. As I have reflected on my losses and deaths I have realized something pretty apparent. My micro-play is decent but my macro-play is terrible. I usually do well early game but I lose my lead quite quickly in the mid to late game as I waste time and don't do what I should. I have looked up several tutorials and help things but nothing seems to change. I have tried playing Jax, as suggested by a high elo friend of mine, to help me split push for objectives and try to abuse my lead. I have had a little bit of success but I came across a new problem. As most people in bronze II are pretty bad (INCLUDING MYSELF) a lot of stupid things happen. As I stated earlier, I almost always do well early game, and have a positive kda, but as mid game rolls around, and team fights become more common I have an issue. I can either split push and get an objective (tower) but leave my teammates in a 4v5 and get yelled at or I stay mid and help my team (In bronze there is usually a huge amount of time wasted because both teams just stand mid staring at each other for a while before any fighting starts) but NO ONE goes for ANY objectives and we usually lose. I probably sound like the usual bronze player saying "MY TEAM IS BAD, IT'S NOT ME!" which may be true, but I try to reflect on my games and my deaths so that I can improve. To be honest, I know I am terrible at league, that's why I am bronze.

You: Why are you telling us all this Legit? Well I know it is a lot to ask and I know some of you may not have the time but I would love for someone to help me identify better what I am doing wrong. I am not asking to be boosted or anything like that, just someone to show me specifically where to improve rather than the general tips that seem to be everywhere in the league community.

Thanks for reading my thread thing! Any help is greatly appreciated
