You can go a long way on sweet tea in my experience, SJ, and thank goodness for that, eh? If you can manage a slice of toast, some soup or something, that will help. It's not surprising you can't eat. Don't worry about it, and don't force yourself at the moment.
I'm smiling, (though there might be something in my eye too), imagining you singing Dancing Queen badly for your DW to make her smile. Did she open her eyes at this point? Could she have actually been rolling her eyes in recognition of her DW's bad singing, while at the same time smiling inside? Even in these darkest of days, there is warmth and humour where there is love.
It will be hard to see it, impossible to imagine it now, but one day the sun will shine for you again, the food will taste good, and you'll be singing Dancing Queen badly, (but with feeling), dancing around the kitchen with your son. It seems that you share such a positive sort of love with your wife, and that sort of love, that sort of person, doesn't ever leave you, won't ever really leave you and your son.
I'm going to make a cup of sweet tea, SJ, and raise it to you all.
