Hi Chris. I'm so sorry that you're going through two cancer treatments. Bloody awful darl!
Don't worry about being positive if you're not feeling it. It makes no clinical difference, and often it seems to be more about making those around you more comfortable with your cancer than making you feel better. Sometimes the pressure to be the 'good patient' is overwhelming...
If you're naturally inclined to feel positive that's terrific. And while 'fake it until you make it' can have benefit at times, if you're not, you're better off putting your emotional energy elsewhere.
I've been told that psychologically you have to lean into the pain and go through it, in order to come out the other end. Ignoring it can lead to problems further down the line, even PTSD in extreme cases.
So I say be grumpy/weepy/negative/angry and every emotion that arises. Go with the flow. The blue sky is there and when you're ready to see it, you will. At least that's what I'm hoping!
Hang in there and stay in touch here. K xox
