I don't like unipolar since something polar always has two poles. So it violates logic. Otherwise good idea.

What about DROWNING? LOL

Depressed mood and/or sadness
Reactiveness, irritability
Overwhelmed, difficulty with memory and focus
Worthlessness, feeling of
No energy or physical agitation
Insomnia or hypersomnia
No interest in what used to matter
Going numb or extreme dysphoria

Just kidding... but still.
