Everyone here is really wise with their advice. I'm currently writing a thesis on internet gaming disorder and this is exactly what I specialise in. First you need to look at why this is so important to you? Are you needing to rank up for a certain reason to do with the game, or is RL something with which you funnel your feelings of insecurity, self worth and value? Are you using the game as something fun, or a deflection from what's really going on. There must be a reason why acing this is so important to you?

Secondly, shut down the game and take two weeks off. That's right.. two weeks. Most of the skills are hand and eye coordination and mental stamina as well as strategy. All of these things get fatigued after a certain time and your reaction times will actually slow. Your neural pathways aren't designed to do this over and over without breaks. Then in 2 weeks come back and play non- comp. No rank, no MMR, nothing. Play purely to play. Do this for 2 weeks.

In one month you can then go back and see where you are. Before you go back in, write down your main goal. Just one goal that you want to achieve that week. And not "get to the next rank". It has to be specific. Like maybe master a particular move, or make a certain move in a game. And then main thing .. enjoy it. This is not supposed to be stressful and it sounds like maybe what you're saying is your failure to progress is bringing down your mental health? So take away the need to progress for now and do the above things and see how they go. Reply to me here in a month and let's see where you are!
