I’m going to put everything on the line here, only because I know what it’s like, and I hope this helps.
I knew something was terribly wrong, but I didn’t know what. I wanted to be hospitalized, but my (so-called) “doctor” had the attitude that I would hate being hospitalized and that furthermore, mental illness was something you should just “pull yourself out of by your bootstraps.” And I was too sick to have it together enough to defy her.
After about six months of agony, I felt like the only way to end the pain was to die. I had never threatened suicide, but I know now my husband was afraid I would do it–but for reasons I don’t want to go into, he believed my doctor that things would get better by themselves.
I formulated a plan, wrote a letter so people would know why I had done it. I was getting ready to leave the house and drive to the bridge I planned to jump off of, and my husband must have seen something in me that told him this was it. He asked me point blank if I was going to go kill myself and I confessed that I was.
He took me to the ER, I was hospitalized–which ironically turned out to be one of the best experiences of my life–and now, with medication, I have been stable for 15 years and live a completely normal life.
So looking back I would say that it was the ultimate cry for help. It wasn’t death itself I wanted, just a way to stop the pain, and for someone who was able to do so, to get me help.
I guess if you boiled all this down, my answer is that if someone is talking about or alluding to committing suicide, get them help. Whether they “mean” it is an open question. That they need some kind of help is definitely true.
If their threats become a chronic problem, at some point you may have to hand them over to someone else to preserve your own health. But that will be easier for you if you know you tried your best to help them.
Hope this helps.
