So this is my second post, and it is not regarding me, I don't know if this is the proper topic to post this in, so you might see me getting this out topics that I feel fitting for this problem.
So, I feel like the friend I have started this account and joined this community for's situation is getting worse, He is in the loneliest place he has been in his life, so I did my best to think what would help him with that and contacted another friend on the internet that I know would keep him interesting company and spout a supportive word here and there, as he is really looking for making a meaningful connection who can be open and honest with and vent to besides me. but, regrettably, I told the other friend that i'm worried for him and that he is skirting the edge of suicide, She toke on the mission and they talked for a bit, and it went great...until all of the sudden he was attacked by the unshakable feeling that she is only talking to him because of his situation, and she doesn't really care for him. While she admitted to him and me and really doesn't come across as lying that she genuinely enjoys his company, rendering his suspicions to be untrue, yet he has made his ears deaf to our convincing attempts, and couldn't stand the possibility anymore, and removed her from his friends list, now his faith in me has shaken and I suspect he is even in a worse place then he started, all because of some proven paranoia about attention because of his situation, not because he deserves it.
How do you deal with someone with that mindset? How do you convince him to believe someone is actually, according to his words, prevents HIS suicide, and not A suicide?
