so nervous!

i have a big swim meet tomorrow and I am so nervous! I know I did awesome on my last one but this time I have to do an ''IM'' which is were you do butterfly down, backstroke back, then breaststroke down, and freestyle to finish the race! I am also do a 50 breaststroke, a 50 backstroke, a 50 butterfly, and a 50 freestyle!( i am getting more nervous as i talk about it) and for me the hardest would have to be, the 100! freestyle! well wish me luck... BYE!
