Be patient, don't rush. There will be time. Since you can't go, just keep practicing. Don't worry, until you really can, then you can sign up.
I know you are anxious inside. And suddenly I understand why there are white hairs. Later I found out that maybe it's because you tend to get anxious, which has caused you a lot of stress.
I hope you can slow down, love yourself well and cherish yourself. If something can't be accomplished for the time being, then keep practicing. Don't worry, take it slowly.
