In reply to Donotello:
I have suicidal thoughts pretty much every hour of the day. Its exhausting fighting them. I can relate to what you say... lots of my friends say lots of well meaning things about mental health on social media, which is great, but often when it comes down to it I think the majority dont know what to say if I open up. (This isnt a criticism, its bloody hard dealing with my thoughts and feelings).
I've fortunately found a counsellor privately who I get on with, I'm seeing her again and have a bit of hope that things will improve. Having a bit of hope is half the battle won I think.
I haven't found the NHS to be particularly useful with my mental health, they generally throw pills at me which I have tried but dont really get a lot out of unfortunately. This may be different for you, so worth investigating.
Anyway, I recommend finding a counsellor if you haven't already. And dont be put off if the first one you see isnt quite right for you. A lot of them do a free first session before committing to working together.
If you want to, you're welcome to PM me. I'm no counsellor, but I get it. Simon
