I think I've permanently damaged my singing voice?

Perhaps she was depending on you to use your talents to make the show a success, and she had you planned into the music or singing portions. By dropping out, you have shown an inability to be dependable, and she has had to scramble to fill your roles with others. It can be difficult for teachers to make last minute changes like this and assure the success of her work with you.

You really let her down. Go to her with an apology.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
