Hi ABitWrong. Sorry that your feeling so crap.
I f you go to A and E because you are feeling suicidal you will be seen and assessed either by a Doctor or a nurse from a mental health assessment team.
I am not sure were you live but when you are assessed there are usually a few options that you could decide together what would help you best.
Sometimes (dependant on your area) there are Intensive Home Treatment Teams which are an alternative to hospital for people going through crisis,consultant ,nurses and OT's make up these teams and would visit you in your home on a daily or twice daily time. You would be prescribed any medication that might be helpful and they will refer to any other help you might need.
Another alternative is a stay in a hospital which is usually not as bad as it seems,you would get a lot of support and help.
The assessment service could refer you to less intensive community nurses or ask you to go to your GP as soon as possible.
You are obviously really worried about SS,if you can try and think of it this way,lots and lots of people feel suicidal at times. It does not matter if you are 60 or 16,have 10 kids or none,you are ill and you need to be seen and helped.
In my experience a referel to SS would be discussed with the person and this would actually usually be on the request of the person to enable them to access some support and help.
No one would want to do anything but help and support you...honestly you don't need to go on like this,please get some help.x
