It lingers around, causing chaos

This feeling of inadequacy seems to linger around
Causing the light to dim and the dark to move in
Why this feeling surfaces is a mystery
But its set off when specific things are seen
Or heard about
It brings on that lost, empty space
That makes itself known only to the person it chooses to affect
It brings out the worst in people
Failure is a big fear of some
Not living up to expectations of those loved ones
All it does is bring out the tears
And the questions
This feeling only lasts a few hours
Come the next sunrise, the light has taken over
Brining the spirit up once again
