There are days when I fully expect to be sad, anxious, depressed. My wedding anniversary. The date my ex-husband came out of the closet. Around the holidays. And there are other times when I just wake up, on a beautiful sunny day, with nothing in particular to be worried about, and it feels like the weight of being a single parent is just coming down on top of me. My stomach is in knots, and I know I shouldn’t drink coffee because it will make it worse, but I also know I can’t function without it on the little sleep I got last night. I mentally run through the list of possibilities of why I might be feeling this way. There is food in the fridge. I am not PMS-ing. I have a great job that I love, and both my son and I are in good health.
