I started playing chess two years ago and i'm currently rated 2100 on chesscom and i mostly play online games. In the near future i am going to play my first big open tournament in a classical time control and the pressure of knowing i will likely (certainly!) lose a few games kills me, does this get better within time? How do you deal with it? Not caring seems unrealistic or a bad sign in general so i don't really know how to approach this
