Fame
If your goal in becoming this kind of mental health professional is getting your own midday television show, we've got some bad news for you: it's probably not going to happen. Your average grief counselor isn't Dr. Phil (thank goodness), she's the kind-faced but slightly eccentric person at your high school that worked in the nurse's office but wasn't a nurse.
Even the counselors to the rich and famous aren't getting their names splashed in the headlines. Part of that is the whole doctor-patient confidentiality thing—it'd be really hard to do business with celebrities when they think you're going to be blabbing about their poodle-related depression to every tabloid in town. The other part is no one really cares about a celeb's particular medical team. You're going to have to settle for being really good at your job.
