Sorry you are feeling rough right now. It always really knocks the stuffing out of me when I make the effort to do something good when I'm in a depression. If my mood lifts to the occasion I also pay for it later. Get some rest and remember the third word in that post "enjoying". Even if it was transient, even if it was about social acceptability rather than a more meaningful enjoyment - you did it - be kind to yourself, you've achieved a lot today.
