Well done ringing them and admitting about the drugs. If they did send you do a drug clinic I'm sure they would help you with stopping.
I hope you don't mind me replying to you it's just it struck a chord as my experience sounds similar to yours regarding the voices, phone tapping, suicidal thoughts about not waking up, and especially the worries over the children.
Try and tell them (the psychiatrist) about these things, I found his hard to do, i think, as DH was there too and I was a bit ashamed of how I was feeling. DH didn't really understand and I think it frightened him. Also I didn't really trust the Crisis team people. But I did say a little and they gave me a course of I think, mirtazapine and olanzapine, a combination which helped after a couple of weeks..initially it helped by making me sleep which I'd been struggling with (how is your sleep BTW?)
Then just trying to eat OK, combined with sleeping, it is good to have someone to share your worries / thoughts with (the crisis team people were quite good at reassuring me) The only thing I found a bit tricky was that it seemed to be someone different that came round each time. They did this useful thing which was looking at evidence for my thoughts, and replacing them with more useful reasonable thoughts, but that might be for the future in a few weeks or so.
It was around this time last year for me that things improved, after taking the meds 2-3 weeks. It was when we had lots of snow, I thought maybe the snow had quietened everything! Then when I started going out a bit (first to a cafe with one of the crisis team people) i started to realise the world was OK, not the scary place I had imagined. Hope this is helpful, we're all different but just thought it might help to share experience and I know, how it can feel relentless like there is no end. Well, it can, and hopefully, will, get better.
