Hi zinco, maybe part of the way you're feeling is completely drained after having done so much, and a bit of a "come down" with being back at home after.............now that would naturally take quite a bit out of a lot of people.
Maybe try to take it easy till Sunday, try to focus on the "positive" of what you've done/will be doing (or just a bit of "escapism" if that's easier) and hang in there.
You were out of it and words from THE WISE: "I just can't imagine it ever ending, yet it does"
Here if you want to talk/some support/whatever!!
