Actually, i vaguely remember them. Was this after he killed the three Kryptonian villains in the pocket universe? Of course, this was before zero hour and before his death.

I don;t remember any occurence in the recent past though.

Suffice to say, if Supes has a mental disorder, not much of a hero then is he? Not ,much of a man. Give him a valium or some other drug and let him space out. Yeah, that would be the right image to portray of a superman!!!
