Good evening and thank you for the opportunity to help in answering your question. First please let me say that I am sincerely ***** ***** hear of your friend going through this as well as what you're going through as a result.
Based on the detailed information you've kindly provided it sounds as though your friend is presenting with a personality disorder in addition to the depression that he's clearly going through. I can sincerely ***** ***** concern about his throwing out the suicide statements and chances are that he is doing so in order to get attention. However, I've learned over the course of my practice that regardless of the behavior and circumstances that it's best to err on the side of caution.
The reason I say that is two fold. The first is the obvious, in that if they are not simply stating it to gain attention and actually do it that would be the worst given that they had asked for help in that respect and were not heard.
The second is to present that you were serious when you had the intervention in the past and that this type of behavior will absolutely be taken seriously and that this is nothing to joke about and certainly not a way to ask for help.
My suggestion would be to go ahead and do the 72 hour hold, especially that he's been on a downward spiral as of late.
I hope that I have been helpful in answering your question and that you found my suggestions to be of benefit to you.
