Emotional burnout

Last year I was in a situation with a very suicidal friend who's family was falling apart. Then later last year another friend was on the brink of suicide and I almost lost him. After 9 months of anxiety and constant dread, I lost connect with the first friend and the second one was doing a lot better. Now after exactly one year after these events occured, I joined this discord server with some really great people. And there's this one person who's really suicidal. I tried to talk him out of it, but I couldn't. He's still alive don't worry. But before I was so good at it, but after that I felt burnt out. It was only a 15 minute conversation. Even though I'm really good at understanding people, I have this black cloud over my head saying I'm not qualified to help. And, yeah, I'm not, but I can at least say something to help.

I don't know. Maybe I'm not ready and need more time.
