Yeh I have told my mother, a lot! I used to think why on earth would you tell someone that but I guess after a while it just becomes normal and you can't keep it in anymore. She wouldn't get me help so I know I don't have to worry about that, plus I'd probably be able to convince anyone I'm perfectly fine anyway. Am also in the UK and they don't do anything these days, even the really psychotic people are still walking around not getting the help they need.
I've also threatened it to another family member, which I know a lot of people view as manipulative-which I don't think was my goal, I'm not even sure I know what my goal was. I think he was saying some really horrible stuff and I got oversensitive and that was my response. I'm probably quite a manipulative toxic person, so who knows, maybe all my talking about it is a manipulation tactic. I really hope not, but will I ever actually be able to go through it? I just don't know myself well enough to even say for sure if I'll ever be able to do it.
