All my friends and family agreed that I should get the main (girl) part, because my personality as an extrovert was so similar. I had practised every day, memorized her many lines, and tried to act as she would have in the day... Then I got an email saying I got the smallest, shyest part. She barely has any lines! I was really upset... And not just because I didn't get the part - because I feel like the other girl who did, didn't deserve it at all. She was the daughter of the director, and got to choose. My friends still think I should have got the part. How can I cope? Please answer soon.
If it's any consolation, you haven't spent a decade working your arse off to face this reality. Regardless of talent, when competition is involved you will find yourself having to scrape the bottom of the barrel to eke out a living without the right connections. The true test of determination is doing so for long enough to get noticed.
