Disappointment

Anxiously waiting with high expectation
  restless and giddy from anticipation
  only to come to the realization
  that unmet desires led to frustration
We can whine, we can cry, we can gripe and complain
  we can sulk,  we can pout and show our disdain
Or just be content and stop feeling cheated
  and be grateful to have all that is needed
Disappointment can be a double edge sword
  it may bring resentment, it may bring reward
  be optimistic and reflect what's been gained
  for perseverance and patience have been attained
