The darkness came, passed and went away
stealing not second of my light today.
I held onto every last drop
forcing the bubble not to disappear or pop
People told me to think happy thoughts
and that idea never quiet worked never caught
so in turn I have a new idea,
its really creative and has lots of appeal
don’t think happy thoughts, think happy people.
the darkness won't come, it won't steal.

You have such a deep subject to work with; depression. Right? That is your subject?
