Quick urgent question. . .

Violin

Hey lovely people.. Please tell me what can I do to help my depressed 21yrs old bf😔. He apparently does see a psychologist at church, but he refuses to talk to me. I have never encountered such, so the only thing I do is just be around for when he needs me, but he still doesn't after more than 2 months of waiting. . . He naturally is not into expressing himself, but this is another level. I'm panicking now coz he has started shutting his friends off too, I'm scared of what's next. Please help me...😢😢 #EDIT: we have been dating for ~4 years, but this started 2 months ago.
