The worst disappointment is disappointment in yourself. That is the reason we blame everything on someone or something else. If we acknowledge it is our own fault we must be the one to address it.
But sometimes you are placed in a corner with no-one else to blame. It is at these times we hurt the most, withdraw the farthest, and struggle the hardest.
It can destroy you if you let it, but it can also rebuild you if you let it.
It can be the most life changing experience of your life when you deal with self disappointment in a healthy manner.
Evaluate, change your actions, and overcome that which is staring you in the face…
In other words, self disappointment will always lead to repentance.
