Overwhelming pending little things

So, I'll be taking like 1.5 week leave starting this 23rd. I am planning to sort things out, life, home, family and giving thought about how to make life less miserable going forward. Lately I've been really struggling to be as productive, it's as if I've lost the fire I had when I started working again last year. I want to know how to deal with this issue. I want to know how to properly reset when these things came at me, and how to manage overwhelming things at once. I want to be less miserable.

1.5 week might be long, might not be, but this is the only time I have before next year. Maybe it's all arbitrary. People says now is the time. It's correct. That's why I managed to ask for that period of leave. Else I wouldn't be able to.
