Back in 1992, I started feeling suicidal. I was 15. I spoke to a friend, who promptly told my mother who got the gp for a house call and a letter for a bed in local mh ward. I was there for 5 weeks while I was started on meds.
My next admission was the following year after turning 16, I was heading down in mood. The occupational therapy group always amused me as it was playing bingo for cigarettes which I kept winning and a couple of mh nurses trying to teach me to inhale.
It was totally different scenario to mh services nowaday. absolute chalk and cheese
Back in 2015, I made an attempt to unalive with tablets, when I woke after 12 days unconscious and was reviewed by mh team, they advised where I made my mistake and that if I had taken X first, it would have definitely killed me but I passed out with it in my hand before I could take it. I was being discharged home to finish the job even though I was only conscious for less than 2 hours now was crystal clear of my intention..
So the threshold for services is very different. As others said it was also prescribed as a "rest" for assessment..
Over the past 30+ years, I've had coma therapy, ECT, "courses" which was basically sit and listen to someone reading word for word from a book but not allowed to chat with other attendees, EMDR which was brilliant but apparently I wasn't improving fast enough (it takes more than 4 sessions)
