Sadly mental health 'services' are way down the list, even lower than geriatric care, when money is handed out. Like we don't matter

. I had the same in the 1990s - GP referred me for psychological support, it took 18 months before the girl phoned to see whether I still required the sessions

and cussed me, said 'yes'. I knew more about health issues than she did but she was very understanding. She offered to keep 3 sessions open for me over 6/7 weeks should I require them, I phoned before the 1st and said to give them to someone else.
Could your GP refer you to a Community Outreach worker or Community Mental Health Nurse? Have a look at MIND web-site you may find a drop-in centre close by.
Hopefully the new med. will ease those intense feelings!
