You are definitely allowed to have your emotional times. And you know what, even though our husbands don't always know what to say or do when we are like this I think they do understand.
Gosh, chemo drugs in your system, grieving for your beautiful sister, dealing with BC, not to mention everyday 'normal' stresses of life! They really should be handing out gold medals for everyday that you get through at the moment. I found I just needed to retreat into a little cocoon to get through treatment.
You need to be kind to yourself and when you have a better day, a little reward can boost you along. I remember one day I had an absolute craving for hot chips. It was winter and we lived a good 25 minutes from the nearest take away. So my husband and daughter came with me and we got fish and chips and sat in the car at a park and had a picnic! It was only simple but I felt so much better for my little reward!
Hope tomorrow is a better day on your 'BC roller coaster'.
Take care. Deanne xxx
