A 3 poem night

I'm not sure what happened today,
it went from good to bad.
I don't know how a day that seems so sweet can easily end up sad.
I lose myself in the emotions of the deep well in my mind,
mixed up with lies and truths that I can't always seem to find.
I know the person I feel I am,
but the person that you see,
how often I asked how I fooled you,
into seeing one so sweet.
You say that I am happy, optimistic, maybe bright,
but inside me I am dying,
I only hang on to the light.
