Support with a model

Good evening, please could I ask for the model I just did to be checked? I don’t think the C is factual enough. Please could you help me with how I could have made it more so and if the rest of the model is okay or not?

C: Mum not emailing
T: She doesn’t want to continue
F: frustrated
A: Not contacting mum, not communicating with her
R: Not effective communication.
