so I am extremely tired, I have had a very long day. here goes... the first 2 hours of school was fine but when i got into girls chior, I had to sing 4 songs and reherse for the concert coming up soon. So after I was done singing, my voice was shot. On top of that, I had to sing again next hour and I couldnt. it sucked. I am worn out..bottom line when i sing, its takes alot of my energy, i dont know why either..
