I didn't call it attention seeking, that isn't a term we use. All people attention seek, it's how we get our needs met on a daily basis. Attention seeking is saying to a partner 'ive had a shit day, can you cook tea and give me a cuddle please'. Attention needing (or care seeking, same thing different Trust terminology usually) is different. They are behaviours driven by mental illness, usually personality disorders, where the behaviour is created by an intense desire for support outside of norms, and then designed to force the other party to respond because of the nature of the risk. You are attempting to force others into behaving in the way you deem appropriate by your behaviour. It isn't working, so now you are highly dysregulated, and without treatment and a personal desire to manage this need, will continue the cycle.
It isn't true to say that everyone who calls for help didn't really mean to die - there are others who are in such great distress that they attempt to take their own life, but the act itself provides some form of clarity, either because of the pain, or because the adrenaline breaks through the distress etc. These people may well then ring 999, or if they feel unable to seek external intervention then they'll make themselves sick, provide their own first aid etc, often at great risk to their health. What they DON'T do the next morning is kick off that they haven't been given attention because of it. Usually they either don't tell a soul, discharge AMA, downplay what happened, refuse to discuss it with care teams etc. These patients are at a very high risk of a further attempt that does end their lives. The patients yelling BUT I WAS BLUE and describing nurses as abusive because they're not acquiescing to their desires require a different process of management, which is as per the NICE guidance for personality disorders. That doesnt mean you arent very deserving of help - but it is different help.
Do you know that personality disorders have the highest recovery rates of any mental illness? It's true. Put your energies into the right treatment and working with, not against, teams and you can recover. I did.
