My son has had a pretty shit CAMHs journey. Won’t bore you with it. Anyhow he is being treated for depression and anxiety with fluoxetine and beta blockers . It was clear that some pretty major complicated intrusive thoughts and anxiety were causing the depression. Started seeing a CP who discussed OCD,did CBT type stuff recommended books etc. Made progress, all good etc. She then abruptly left CAHMs. He has now been placed with a manager, gone down to fortnightly and she said she will get to know him and try a combination of approaches. Seems to be very different in approachHad a letter saying he’s being treated for anxiety. 
Really confused and he is sliding so very worried as he was on the floor depressed before.
Should I ask for more clarity re a diagnosis and treatment plan?
