Hey Tillsall67, just pop the @ sign in front of the person's name and they'll see your post. The only time you don't do it is when it's their discussion.
The beginning is the absolute pits. I was a wreck the first few weeks. Petrified then furious then crying all the time. But it passes. As your treatment plan comes into focus and commences, as the initial shock wears off, and as you just get used to being part of the cancer world, the adrenaline coursing fight or flight agony of the start fades. There are bumps and shocks and nasties along the way for many of us (I have completed active treatment and am comprehensively down in the dumps...), but nothing compares to the bone chilling dreadfulness of the beginning.
The thing to do now is to work out for you what helps the most. For some it's knowing as much as possible, doing lots of research, asking lots of questions. Meditation helps many, there are some good apps available for your phone (I like Headspace). Some people throw themselves into exercise. Distraction was the only thing that alleviated the pain I felt at this time. Mindless tv shows were a godsend. You can enlist your friends to distract you. Journalling/blogging helps lots of people. Do you have a hobby that you enjoy? Push through and keep doing it.
For the night horrors I did a lot of 4-7-8. That's breathing in for four seconds, holding it for seven seconds and exhaling for eight seconds. Do it five times in a row. It provokes a physiological response that calms the nervous system.
No one can tell you you're going to be all right, but take comfort in the statistics that 90% of us are still going strong five years from diagnosis.
Whatever happens we're all here for you, even at 3.30am! Deep breaths, and hang in there. K xox
