Never far away

That concern about recurrence is never far away it seems... 

For the last few days, I've been really, really, really tired for no reason that I could identify. So, my mind went into overdrive.. is this it? Has the cancer come back somewhere else? And then I realised. I've changed my hayfever medication. 'May cause drowsiness'. It's so easy to think it's happening again and start to worry about decisions you may never have to make.
