@Tommy, I had those same thoughts repeatedly when I got my diagnosis. I initially totally lost it and cried for days and as I processed it,I went through a range of different emotions. Disbelief,anger,grief to name a few. Tests and waiting for results were/are so stressful and I have cried often through these last 6 months. My whole life changed pretty much overnight as I was working overseas and had made the decision to come back to Australia for medical care.
As Afraser said above we all process differently. I have found it helpful to take one thing at a time whether it is just coping with a day,chemo session or an upcoming doctors appointment.I am focusing on the good things as much as I can but there are those days and times when that’s hard and that’s ok. I have also found it therapeutic to do the things I love,so if you do and can do that,it might help. Most importantly I have my faith and that is what helps me the most. As I write this I realize that I don’t have the answers but can so relate with feeling like you are and wanted to encourage you somehow. This group is great and has helped me on my journey for sure.
Saying a prayer for you and sending my best wishes x
