Being blacklisted is a special thing. I'm going to try to describe it to you. First, you must realize that you'll never know what hit you. Your agent will smile and tell you to keep checking as work fades from both your memories. The position of importance you felt when you came into his office doesn't exist, and the phone rings - welcome excuse - the visit is over. The money that poured into his pocket from your labor is spent or stashed away. You are now expendable. Heartless - yes, and the net is so strong you cannot penetrate it - ever. You must redirect yourself and if you have the strength and luck, you may push through in spite of all. But it is catastrophic because it involves the ego, the actor's altogether necessary spine.
