Me, to myself.

My mood had been bright,
I'd felt so free.
To be honest,
I'd felt more like me.
I'd held a lightness,
Through the day,
As if that was,
My standard way.
As night drew on,
As eve drew close,
The mood grew dark,
And I morose.
What have we done?
Me, to myself?
This is not good,
For mind or health.
