Disappointment is a human trait. 
In pure spirit form there is only recognition, observation, and learning.  Events are neutral.  With your human thinking you put a so-called “spin”
on them.  Did a thing or event meet your
beliefs and expectations or not?  Those
in spirit are never disappointed in you. 
They know that you are here to learn and grow.  Even if you do not learn and grow from those
things that disappoint you, you are still loved.  You are still worthy.  Do you like disappointment?  If not, choose to see it in a different
way.  Try this.  You will not be disappointed.
