Remember that anything worth doing is worth half-assing it. Eating is worth doing, so half-assing it by eating chocolate bars and Trader Joes frozen meals is fine and dandy.
Finding some kind of pleasure is nice, so half-ass keeping up your house by not taking down Christmas decorations is fine and dandy.
If you have to do anything in this season of your life, give yourself the grace and forgiveness to allow yourself a half-ass job. There will come a day you can breathe deep breaths again. Until that day comes, half-ass through it.
