I don't know what to do and need help

I found out my friend has been feeling suicidal and overwhelmed by everything. He seems better now but the things he was talking about were only a few days ago. He has told a few people and I think they have helped him and I have tried my best too but I don't know what to do or say. I hope none of the large number of fake people look in this part of the forums but if they are, please don't talk to me.

I need help and I would like it if you could pm me any advice
