It sounds completely OCD, and I'm sure it could be classified as such...but when I'm down sometimes I will feel almost instantly better when I clean. I totally get into my head and get lost in a zone that helps me sort through what's at the root of my sadness. The same thing goes for working outside in the yard. I can have little conversations in my brain and simultaneously work stuff through that can get stuck on a cellular level. Generally though, a good talk with my partner, some snuggle time with her and my girls, sometimes a good cry...and I'm all set!
And if all else fails, I have a heart to heart with my mom. She wasn't always the best mom but now that she's gone she's a fantastic listener!
