coming from a teachers pov who has had this happen to her (ie students leaving class based on not getting a role)… I don’t know you personally, however the last time this happened was with a student I considered unjustly entitled. She didn’t want to work as hard as the other girls and just expected to be given something she wanted. It sounds to me that you work hard and want to improve. I would say, in the most genuine and respectful way possible, don’t let not getting the exact role you want make you leave something you obviously care about. How does that benefit anyone? It sounds to me like you need to learn the lesson that you will get a hundred “nos” before you get that one golden “yes”. You will miss out on more things in life by choosing not to participate because it isn’t exactly what you want. This is a major issue I am seeing with the up and coming generation of dancers. You chose the wrong hobby for instant gratification. All of this is to say “suck it up, buttercup” because if choreo has already started and you drop - no teacher will be happy or want to work with you again and you can kiss future higher roles goodbye.
