I'm not sure if this is the right forum for this, but I have a longstanding friend whom I am not that close to (at least recently) who is definitely depressed and becoming suicidal according to other friends in our circle. We all used to work together and over the years most of us have either married and had kids or otherwise become settled, and our friend has remained alone and slowly gone downhill and increasingly pushes her old friends away if not actively antagonises them. Some of our circle simply refuse to deal with her now but I worry that she will end up sectioned or dead. What can we do? I believe she has been in some form of therapy and know she has taken anti-depressants, but clearly this has not helped. Some of us think she has bipolar disorder and needs more serious help.
Has anyone been I this situation? I almost feel like we need to stage an intervention but I wouldn't know where to start and I wouldn't want to do anything without a plan. I just worry that one day her flat mate will be forced to call the police and this will end with her being sectioned. She has no family here and really no one to rely on apart from friends. We are all in our forties now. Any help or advice would be greatly appreciated! And sorry for the long post.
