It's hard to question someone if they go insane, but the bottom line is that he's sick of being rejected. It's a case of looking at a single negative and ignoring all the positives.

[ hint hint, Sasuke... anyway. ]

So if you could shove some positivity at his face, that'd be all I need from you. You can go back to napping after. You said he's done so much for you and everyone else, but it looks like you went through something without him and made it out okay. I'd like it if people stopped relying on him too much, but being there for friends... should be fine.

Just tell him why you want him back. Not for everyone else's sake, but yours.
