Before you ask: Lvl 96, .84 K/D, 61% W/L ratio, and 11.6% HS accuracy. I'm not good at the game. I honestly really regret picking it up. I was stuck in iron because I threw my placement matches, and got to Bronze 2 within a week. 
However, I feel like I'm not improving at the rate I want to be. I feel like I have impostor syndrome. I play unrated because it helps me relax and I really have fun playing it when I'm relaxed. But I also love winning. But me being at level almost 100, and still being in the worst rank has me feeling a bit down. I know I can get better, and that I can improve. I also know for 99.9% that I'd be able to climb to silver 1 easily if I had better aim. Can I get some help? Please. I need tips to climb.
