My own experience with this disorder, has not exclusively consisted of mania or even mere contentment.
In fact, it's a constant dance of survival by any means necessary in my own head.
For example, I can look calm to people, yet my inner turmoil can keep me awake...inside.
The video below has lyrics of what myself and many others go through each and everyday.
Not always a physical dance, and even the visual portrayal of a mind in distress.
Whether one is living to exist or existing to live,
I know I am not alone.
We see the same from different eyes.
