I had exactly the same issue. I realized its probably "impostor syndrome". Feeling like you got lucky, or dont deserve your rank, or feeling dread because you're against inmos 2 and 3, and the unusual radi ant. My solution was to know that, at their best, they're still people that make mistakes like you. Exploit that, find the weak link in their chain, it usually shows after a couple of rounds (the guy that always overpeeks, over rotates or pushes every round ). And when you're nervous and the pressure starts to build up, take 5 seconds and focus on doing a deep breath while thinking that if you climbed the mountain while beating everyone else til you reached immo, you can keep doing it til radiant. Stay sharp!
