I was a bit annoyed and became more so when I went to the box
Did something happen? Why were you annoyed?
I felt annoyed when I didn't get something I wanted.
Somethings you don't get what you want or need, so it is okay to not be happy when that happens. Nobody has to be happy all the time.
Are you saying that I don't deserve what I want?
No I think that you should not expect to be happy all of the time because that would be unrealistic.
