Hi I know it seems a long way away but your Gp can refer you to a crisis intervention team if she thinks you require hospitalisation. Could you talk to your counsellor about why you might be struggling with suicide right now? Does your counsellor know?
I know 24th July seems a long way away but that is really not long in terms of NHS referrals... having had to wait 16-18 weeks for an urgent appointment for my child who was very ill, I am aware how overstretched the NHS can be and when desperate it can be horrid waiting but knowing a date, does that help?
In the meantime if you are really struggling go to see an out of hours gp who can refer you to the crisis team for assessment in your area anytime between now and the 24th - your gp is not correct, there is more they can do than tell you to wait until the 24th. Crisis teams are in every area, but it would be a different person you see each time, including males on their own in yoru own home.
