I personally don't trust them because they never cured me of anything. When my parents divorced in Middle School I stopped caring about doing homework, and started flunking.
It was a crazy time when the courts bled my parents dry taking advantage of the feud, and they even assigned me my own lawyer. (For what?! I only met him twice! And I was a kid for crying out loud, what did I need a lawyer to represent me? I just needed time to decide which parent I wanted to live with…)
When I opened up to my lawyer, he referred me to his psychologist friend in the same town, who my parents eventually thought was just a way of making sure he could make more money. He had a plush office, with relaxing paintings and so forth.
By then I had met a psychiatrist who had insisted on giving me unnecessary drugs to cure my migrane headaches, since tylonel wasn't enough - (turns out that when the divorce ended my migranes were gone), and a guidance counselor at a new school who I barely talked to, but who was biased and immediately thought I was a trouble child. He'd be very nice and fake to me, and then privately tell my parents, "We don't know what he is capable of," and suggest sending me to a foster home.
I had by then decided to refuse to completely open up to anyone in authority. Dozens of sessions, paid for by the court at via my parents, where I guarded my feelings, knowing anything I said that was out of the ordinary would probably prolong the divorce and worsen my situation. I just wanted them to get out of my life.
Since then I've felt if I need another Therapist, I can befriend some older woman and safely unload my problems to her. No more drawn out sessions that are more to the benefit of someone else. No more tempting the government apparatus to wreck havock on my family's savings.
