Not sure this is in the right section. How do you make your loved ones come close to understanding what it's like to be depressed and the impact it has on your life?

Over the past few days my depression has worsened to the point where I have been spending more time in bed and really am struggling to get things done. My husband has never experienced depression. Quite the opposite, he is very cheerful, outgoing and a bundle of energy/activity (when we met I was stable and very active).

I think he is frustrated that I haven't gotten some things done around the house recently. How do I make him understand that it is the depression and not really me? I am worried my depression, and now coupled with my chronic migraines, is going to affect our marriage. We have been dealing with my depression for more than 2 years now.
