Hello @azkidney57,
What works for me when I wake up in the night, is a meditation app with bedtimes stories. At times, I will also read a book that does not interest me a lot. Both seem to work to stop my mind from racing. If you can get something to work, it will reduce any tiredness you encounter at work due to sleeplessness.

I am glad to hear that you have some friends and family that you find supportive. I found that was supportive prior to my diagnosis, is certainly not the same post diagnosis. In fairness to some, they simply do not understand how a life threatening diagnosis changes us and our priorities.

I will keep my fingers crossed that the results of your scans are in your favour.
