Edit: my friend is safe now, so thanks for the support!
I've reasons to believe that someone who I was playing with has suicidal tendencies. I have not heard of them in the last couple of days and I'm getting worried. I've tried to get in touch with everyone on his friend's list and even contacted Playstation support in hopes they can reach him.
I'm kind of scared right now and can't sleep.
Is there anything else I can do? He lives in France and I don't know who I can contact since I don't know him in real life.
