Currently stuck in the dark. Though I must add, this is slightly exaggerated. The bright within does shine through in the right company, on the right day. However, lately had been rough.
I only added the final line as kind of a sign of hope. to show that I'm not too far gone. Originally I only used the three lines, but tried to use words to kinda cover light and happiness more universally. I'm not great at poetry so if anything needs explanation or description I'd be happy to inform.
Also, as a comment chat thing pointed out below, this did turn out a bit lighter and less, depressing, than I intended.
