The help you requested from a friend may have not materialized, and that may be bothering you today more than the fact that your task has not been completed. The absence of someone you needed - someone you have been there for in the past - may hurt you deeply, Libra. Try not to take it personally. Try to imagine the reasons this person may have had to decline, and extend that compassion to them. You will probably learn soon why they were not there for you, and it will make perfect sense.
