Strategies for Solo Ranked Climbing

Hello. I have been playing league for a long while now. I am not pro but I am not bad either, l am open to help and suggestions. While I enjoy a good game and getting outplayed helps me learn, I have noticed a lot of my games are not lost because of the game-play. I seem to get into games where the teams are always fighting each-other, someone leaves, or for whatever reason someone gets mad at x and decides to stop trying, so on and so on. I don't really know what to do about games like this. I can keep playing it out as best I can, then people scream at me for not ff'ing and trying. They in turn just start feeding to end it quicker or not playing.

Over the last few seasons I have been around mid gold more or less, I am asking for help because if you look at my match history, I am on track to lose all of my gains. If I get into so many games that are decided because of attitudes and infighting my question is, is solo queue ranked even worth it or is it 100% random. No matter my performance it seems to have 0 effect on the game, only peoples attitudes do. I am getting really frustrated with this and honestly, I don't even talk because I will get reported for some reason for trying to calm people down or focus them on the game. Is this just part of the game now, like 40-50% of games are decided by peoples attitudes? If that's the case whats the point of solo queue ranked anyway? It clearly wont be representative of skill levels because you have no control over the games outcome.

Any help is appreciated before I lose my mind and just go back to DOTA.
