My DD was under CAMHS and I wasn't impressed, to be honest. Her therapist was always "training" so couldn't do the regular appointments. Surely, they need to train before actually seeing children? DD was seen by one of their psychiatrists, who gave her a diagnosis and said that she needed a course of specialist therapy. What she was given was NOT what was needed, despite the fact that I repeatedly asked for months about it and reminded her therapist that their own psychiatrist had ordered her to have it.
Instead, we were given utterly pointless family therapy sessions which gave us no answers or guidance on how to deal with DD's mental health (Google did help us, however). It eventually turned out that the therapists did not accept their own psychiatrist's assessment of DD's mental health and instead decided they knew best.
I think that they didn't fully understand what she had been diagnosed with as they answered questions I had, which turned out to be wrong.
The therapists caused DD to have an almighty meltdown, that could have ended in her death it was that bad, and then were nowhere to be seen. They wouldn't reply to text messages or phone messages and, when they eventually did, it was to say contact the police. Bloody useless!
My DD stopped going as she felt that, although her therapist was a very nice woman, she wasn't being listened to and they had her on a course that they would finish, regardless of whether it was needed or not.
CAMHS need to start listening to parents and their patients as they have the power to help or harm the people that they see. The only thing I am left with is the (futile) hope that DD will somehow grow out of her mental health problems (I know it doesn't work like that) as they never gave me any kind of "light at the end of the tunnel".
