How the F*** do I climb now?

Was gold 1 40 lp and could smell plat...BAM 4 days later gold 2 0 lp and I'm afraid to queue for ranked....I am literally playing better now than the past few weeks I climbed to gold 1 and seriously confused....I keep losing every game and I don't understand how I can possibly win any of these games I've had.You can look up my statistics and say well you died a lot in X game and Y game but having played each game and rewatching replays,I can tell you my deaths were not preventable due to stupid things like not warding,mechanical outplays or any form of tilt. More so lost teamfights because its 3v5 under turret since yasou thinks it a good idea to split when the inhib turrets being wrecked and lucian over here already got picked farming top lane.

But you have the wrong attitude! you just need to solo carry!Just git gud. This is what people say..Each game I enter I think to myself I need to take responsibility for my mistakes and not blame my team..I refrain from flaming,When someone is flaming me I try to calm them down and mute if they don't.I play to the best of my ability and in any one circumstance where its simply me vs an enemy in any form of outplay 90% of the time I come out on top.And I play on 130 ping on average too.I start each game in champion select trying to get the team in a good mood where everyone communicates. What do I get thrown back at my face?More flame, people ignoring pings and diving anyway, no one replying in champion select and insta locking champions that don't fit the comp. I CAN say its all my fault and its not my team, but that doesn't change the fact that YASUO IS SPLITTING BOT WHEN THEY ARE PUSHING NEXUS.

Maybe these past few games have been a statistical anomaly where we just have had the worse team due to unlucky matchmaking.But it makes one question how much power does a player have if they are not at the highest or near highest level of skill...Perhaps this is why league players have the stigma that anyone below diamond IV is trash even though statistically speaking anyone above silver 5 is above average?All this loss streak has done for me is made me question what % increment does skill and game knowledge actually have in determining if someone is climbing below whats considered top tier play?
