It may help to have a look at these two pages on the forum: Suicidal Crisis and Mental Health Forum - Getting Help about what to do if you're feeling suicidal, or if you need emergency help. I hope you can use the forum for support during this difficult time.
If you’re thinking about suicide and are in immediate danger, please call your local emergency number (i.e. in the UK call 999, in the USA or Canada call 911, in Australia call 000 and in New Zealand call 111) or call the international emergency number of 112.
If you have been affected by the contents of this thread and would like to speak to someone about your feelings you can call one of the following helplines:
In the UK and Ireland, the Samaritans can be contacted on 116 123.
