I know how you feel. I have felt that way myself a lot lately. It is hard to be in that depressed mood and not be able to pinpoint any cause or contributor to why you are feeling that way.

My husband has been asking me a lot the past few days 'what's wrong?' and says it seems like there is something really bothering or upsetting me. But I just feel foggy and sort of in a daze, and sad. And I have no idea why. I have no clue how to talk about 'what's wrong' when I don't even know what it is.
