Sorry no one has replied to you....
As you have sadly discovered obtaining the help and support you need from CAMHS is very difficult. My understanding is that resources are extremely stretched.... and only when things are to most rational/normal people completely and utterly in the RED zone does support seem to be forthcoming. I would hope after 1 year on medication an assessment would have been made to determine if therapy would be beneficial, I'd also like to think that a plan would be in place as to what support was going to be provided in the future and when.
I'm sorry to say that you need to continually keep making your case, stressing the severity of what is happening to you all. I truly wish I could say something different.
I don't know if you have tried the following and please forgive me if you have already....
If nothing else it may help to convey (again) to others what you are all going through.
