This may sound outright silly, but by studying what euphoric hypomania is like (as opposed to the dysphoric variety), I'm learning how to define what my unipolar depression really is (as well as how to tell it what to go do with itself). It is basically the absolute opposite of euphoric hypomania. I almost feel like wearing a bracelet labeled "WWHD" meaning "What Would Hypomania Do?"

Hypomania: "What could possibly go wrong?" My Depression: "What could possibly go right?"

H: "That looks like fun!" MD: "I bet that won't be worth the effort".

H: "I feel so alive and I love me today!" MD: "I suck. I'm going back to bed."

H: "The world is full of exciting possibilities". MD: "I tried that, it didn't work, it never will. Guess I just fail at Life."

H: "With effort, anything is possible!" MD: "With effort ... I will just feel more tired."

H: "The world is so full of vibrant meaning. You just have to look". MD: "It's all so futile and meaningless. I'm bored."

See how this works? Sounds completely daft, but it actually works!!

(MD: "This is the absolute most embarrasingly stupid post that has ever wasted bandwidth on the internet. You're being a Pollyanna and also annoying people. You always have to say dumb stuff don't you? It won't work, you know.")
I'm not trying to romanticize genuine and disruptive hypomania, by the way, but ...
Waving my bracelet, Depression. In your face! Like a BOSS!!! And maybe, just perhaps, somebody out there smiled today, or even ... giggled a bit? Did I make a difference today?
