At least i am on the forum and not dead yet
And that's great!
But: You say you don't want to talk to the Samaritans because they "know **** all about type I". Your main problem isn't Type 1, though; Type 1 on its own is never going to make anyone seriously contemplate suicide. That will only happen if Type 1 comes on top of something else.
What you need help with is the severe childhood trauma you've mentioned. Yes, it would be ideal if you could speak to someone who both understood about childhood trauma and understood about Type 1; but what you absolutely need, asap, is to speak to someone who understands how to help people with childhood trauma.
Josh urged you to ring Diabetes UK, and you replied, "How is a call going to be different from posting on the forum". Well, if you rang them and told them what you've told us, they might be able to help you find counselling or therapy which could help you in dealing with both Type 1 and trauma.
Alternatively,
https://www.mind.org.uk/information-support/helplines/ : you can ring Mind at 0300 123 3393, or e-mail them at
info@mind.org.uk . Tell them you've been feeling suicidal, you need help dealing with childhood trauma, and ask them where you can get help near you.
Mind also recommends this organisation:
https://napac.org.uk . As you'll see from their home page, you can ring them at 0808 801 0331; you can also e-mail them at
support@napac.org.uk .
If you can't cope with the idea of speaking to someone on the phone about it, or even e-mailing, NAPAC recommends this secure online forum:
https://www.havoca.org/resources/forum/ .
I hope you will try at least one of these, and that you will let us know how you get on. Wishing you all the best.
