Play – t causing r ???

My daughter tried out for a play. I am looking at a model based on her conversation with me abiut it and I’d like help with the model please, I’m working to understand how the T causes the R.

C: tried out for part in play
T: i want to get rhe part and im afraid i won’t
F: stressed
A: worry, runinate
R: worrying
Im not sure where this leaves her. Id love to help coach her to a more peaceful thought, but given i havent yet figured UM out thought id ask for support. Im particularly unclear how her t causes her r. Thank you!
