Another interview

Had another interview today. For a coffee stand. Thought it went well. Guess it didn't. I cannot understand this process. What is wrong with me? Have I really lost it? I go to interviews and the people say, "We will call you at such and such time.". But they never do. Not even to say they don't want me. Starting to think that the monster is peeking out of my eyes and the family just isn't brave enough to tell me about it. I mean, come on? I went from incredible, to not working for almost year. Will I ever come out of this slump?
