This is very hard to answer because individual circumstances are always so different. In my case, I got over the depression in about a year but still deal with chronic pain daily. I can’t really say what I would want in your friend’s circumstances.

It’s hard to say what your friend wishes. I’d say explain one more time how you feel, how much you care, etc., and if you don’t hear back, it may be time to leave him alone. It could be what he wants. I’m sorry you are going through this. Best of luck. I hope he gets in touch.
