Full stop. Dancing takes years of training and dedication just like any other sport. Ballet, tap, modern, jazz- all of it. When any other kid of athlete spends the majority of their life training for their sport, there is a good chance they are not discouraged from stopping or pursuing something else. If dancing is your passion, keep at it. There is no reason to stop. As a physical therapist who has been there done that, it's my job to make sure you stay with your passion.
This is a picture of me after taking a point class after almost 20 years. It was just as hard as I remember.
