Um…parent issues anyone?

As the school year is drawing to an end, I have lots of things to look forward to. Visiting family, hanging out with friends, and the lack of school work. But I also have to start practicing and working on auditions material, which brings me to this.
My mother has already agreed to let me audition for a k-pop entertainment company as long as I do it all myself. But what if I actually get in? What if I’m accepted as a trainee, would my parents even let me continue on my dream, or will they bar me from leaving.
This is the stupid thing, my parents always agree with something, but once I actually succed or choose to do it, they forbid me from actually doing it. I’ve done already so much for this dream of becoming an idol. I’ve joined 3 dance classes, started choir, and have improved my speaking abilities. I’m learning Korean and brushing up on my Chinese. I know how to present myself well. With all of this, I surely make it in as a trainee, but my parents will suddenly make an excuse of why I CAN’T go as a trainee and pursue my dream
They just want me to stay home. Attend college. And get a good profession.
I’m sick and tired of this.
I want to be able to 1) start a solid and true carrer at my age and 2) BE ALLOWED TO DO IT
Whatever.
