"Would not recommend Kingston A&E for anything."

I went to this A&E in Kingston after taking a rather small overdose (no suicidal intent / just to forget a few recent sad events of someone close to me dying and a lot of other little things / pressure that added up) and a friend who phoned me called an ambulance as she said I was slurring my words. I was treated brilliantly by the ambulance crew but when they arrived. When I arrived at A&E I was put it this room on a chair and within about half an hour I was assessed by a psychiatrist and cleared and still slurring words and couldn't walk that well / unsteady on feet. The psych cleared me and I was asked to leave hospital as I refused blood tests (massive fear of needles) I asked to use the toilet and fell in the toilet and had to pull emergency cord. Two people came in and helped me up. Put me in this chair for about half an hour and then someone who I think was a doctor told me to leave. At this point I still couldn't walk and they literally watched me stagger out of hospital having to lean against the wall to hold myself up. I fell over again once on way out and was helped up by someone else and they still let me walk out the hospital. In summary, I found the ambulance crew very professional and respectful, The psychiatrist should probably not have assessed me while I was ‘intoxicated’ (or they don't in St Heliers hospital or St Georges hospital) but I found him to be very polite. It was the other doctors / nurses who I thought treated me with no respect and if someone has taken a substance and can't walk, can’t see that well and keeps falling over should they just be asked to leave hospital in a clearly unfit state like that? I would appreciate you reviewing your procedures surrounding my treatment and me being asked to leave as I left in a state where I was clearly not well enough to cope safely in getting home.
