I won't repeat what has already been said, except to say that it was a stroke of genius to have Lois dealing with her own trauma. It's her experience that allows her to understand Clark as well as she does. Perhaps at some point she'll need to let him in on some of the details of what she's been through. He needs to know that he's not the only person who feels inadequate sometimes.
Part of Clark's problem is that it's almost impossible for him to distinguish between the things that are truly unique about him because of his alien origin and the things that are 'common to man.' Flying is unique. Not being able to save someone you love is common to man, but he might not realize that. Actually, dealing with bigots is also common to man, but he wouldn't think of that. Lois and his parents are the only counterexamples he has to refute his very reasonable assumption that 'All humans will hate me because I'm an alien.'
