I couldnt find any email to you or a contact in your blog so I´ll answer you in here, hope that is ok?
So, its always hard to say what another person should do and it´s up to you and what you really want with your singing and what your goal is. But when you write your obstacles: that you cant go that day and about the weight all I can say is that if you feel in your stomach and your heart that you want to try out for it - GO!! Fix so you can go and dont care about the weight cause if you can sing and feel confident they wont even care about that.
My advice to make a great audition is:
- Dress in clothes that make you glow! Dont put on something you dont feel beautiful and comfortable in. Do not dress in something that is not "you". They want to see YOU and who you are so dont try and be someone else;=)
- Be prepared for anything. Choose a song that shows the best in your voice. If you have a great strong and high rocky voice, go with a song that shows your whole register. if you have a beautiful soft voice, choose a softer song that really shows your way to use your emotions. Do not choose a "to hard" song. That is: don´t pick a song with the hardest notes to reach cause you will (probably) be nervous going in to the jury;=)
- Also prepare to have another song up your sleeve if they say that they want to hear something more from you. Its always really hard to find a song from your head when standing there feeling nervous.
- And if they dont choose you - dont be discouraged. Just take it as a really good way of learning to deal with the whole auditioning pressure, cause you will probably do some more of them in your life;=)
And last but not least: if you go - GOOD LUCK! And know that I am there with you cheering in your head every single time you feel nervous;=) Go girl! And give them everything!
