Daisy, I've just read all 11 pages of your thread and am feeling for you.
For all the awful, nightmarish horrors you've described the one that upsets me the most - I don't know why - is your mention of the staff 'making' patients dance for them.
I know just what you mean about floundering amongst the wreckage of what used to be your life. I'm still bumping along the bottom; this is yeeeears after finding myself in a predicament like yours. "Care in the community" is an insult. More like "Chuck you back in the shit, good luck, loser!" I don't know what idiot failed to consider what happens to vulnerable patients in the "community", but I hope they didn't end well.
OK, rant over. I managed (too late, but better than never) to get help from two sources.
One was the CMHS, who gave me 26 sessions of very good psychotherapy and a social worker. I may only have got the care worker because I was homeless but it's worth trying. They support you with practical stuff. Mine was fantastic. She helped me sort out benefits and find a house.
Once my therapy ran out, I got visits from a Mind worker for six months. This was less to do with practical help than mental & emotional support but, again, she was great - I managed to start dealing with things, on by one.
I have also rung Samaritans a lot, and will do again when I feel that bad. It's only talking but, often, a good listener makes a big difference.
I'm amazed you're not already receiving CMH services. To access them, see your GP to get a referral.
To access Mind, contact your LOCAL branch from this page.
Also try any other relevant organisations that aren't already on your case :)
You must get outside and interact with 'normal' people each day, even for a few minutes. A short exchange about the weather with a checkout assistant will do!
And keep writing. It helps, doesn't it. Sending you my best. x
