Lottie, I think JJ is hard of hearing and finds it difficult to use the phone and that is why she is hoping her friend will help her out with this.
Also, when you are suffering from depression (as you probably know) you know you have to do certain things but you really can't be bothered, especially if you are having a bad day.
JJ, your depression will not go away by itself so one way or another, you need help and it's down to you which way you want to go about it. I hope you manage to get the help you need. xx
