Restee I agree.
I also think the documentary should be taken in context - of course it's going to make anxious and depressed people more anxious and depressed to tell them them meds they thought were helping might be doing nothing or hindering them instead.
I'm not saying that it's necessarily irresponsible for Panorama to make the documentary (although I haven't watched it yet so will reserve judgement on that).
However, I do think that people who are on the meds (and who are obviously going to be interested in any new findings about the meds they're taking), it's important to keep in mind that the nature of anxiety and depression is obviously going to affect the way one views the documentary and one's own situation and medication choices that the documentary might have commented on.
I always have to 'read' my immediate reactions to things like this in the context of my anxiety, because I find that otherwise, my anxiety (and ADHD, ASD, etc) can take over and I end up making rash decisions that I can come to regret later.
I also have to remind myself to be very wary if I've done a complete 180 on my attitude to something very suddenly or based on one new piece of information, as again I know for me, this can indicate that my anxiety or black-and-white thinking is calling the shots. It might be that I continue to feel the same way once the initial anxiety has dissipated, but I just find it's helpful to be aware of my reactions to things in the context of my own anxiety.
