I am sorry that you are feeling discouraged
I really think that person was trying to help you put things in perspective, even if he/she was lacking in tact.
I think it's great to have a dream. I envy you your talent- I would love to be able to sing. Unfortunately, as pointed out by Cindy, BR, and Mona- your dream is to breakthrough probably one of the most competitive field there is.
My cousin is an Opera singer. She's got a voice that literally makes me weep- it's that beautiful. When she sings Ave Maria, its like the Seraphim are singing. She graduated from Julliard and also has a masters in education. She teaches music for a local Catholic school because despite her incredible voice, she hasn't yet made the big time.
She hasn't given up on her dream - she's planning a summer tour with an Opera group to go to London, Switzerland, Germany, France, and Austria this summer. But she was wise enough to realize that she needs to be able to pay the bills while she's pursuing her dream.
I know it's hard to think beyond your dream and face reality, but I really think you need to think of things you would like to do while you are trying to make it in show business. I'm talking things other than writing or trying to work in animation- those jobs are also extremely hard to find. I have won awards for my writing. That and a dollar can buy me a coffee at Dunkin Donuts.
How are your typing skills? Do you have experience with programs like Word, Excel, or Powerpoint? You're going to need a job that will clothe you, feed you, keep a roof over your head, and give you a nest egg in case -god forbid- something happens to you and you can't work for any period of time. Working entry level at Disney during these economic times isn't going to do that for you. You need to have marketable skills to enable you to adapt while you are pursuing your dreams. If you don't have them then I would suggest you get them. Plenty of Community Colleges in FL offer classes in Microsoft programs. Learn them and I bet you'd have no problem getting a customer service job - perhaps even at Disney.
I'm not trying to be mean or tell you to abandon hope. Quite the opposite. I know what it's like to have a dream. I want to be a Historian. But I also know that it's a long hard road to accomplish that goal and things might happen and I might never get there.
I don't like working at a Network Operations Center. Trust me on that. But I have to do what it takes to get to point B from here.
Good luck!
