i solo qued for a long time and after a while i just got better and better, soon i was level 10. A couple years back i dropped from level 10 to 5 twice while solo queing. Then i just gritted my teeth and kept grinding, got back to level 10 both times and now i'm good enough to never drop from 10. I played so much that i got consistent, only hard work will give true skill. There is no easy way to get good. What i do tho is try to lead a healthy lifestyle and keep a clear mind so that i can think better in-game. That's why i eat better, exercise, try to get enough sleep every day and try to stay positive. When you have a bad mindset you will lose like 90% more games (speaking from experience) When i stayed positive, climbing was easy. If others are toxic, just don't give a fuck about them, mute them if you have to and play the game with the rest of the team.
