The real questions here are:
why do you think your king is unsafe?
why do you think you gave up the centre?
By allowing black's knight to capture the E pawn, didn't I give it up? Because as a result, I just have one lone, unprotected pawn in the center. Yes, it can be defended with the B knight; but that would keep me from using it. My queen is in the center, but Greenpawn has said that the queen (typically) shouldn't be used for defense, only attacking.
The king seems unsafe, because it doesn't have any pawns nearby to protect it. Meanwhile, black's king has a neat row of pawns nearby, especially on black's queen-side. I can still castle, but even then, it won't be as tucked-away as castling typically makes it.
Basically, just looking at white's pawn structure, vs. black's, white looks terrible. And if black castle's queen-side, he has a lot of pawns protecting his king. Maybe I just have to get out of my head, that pawns aren't the only pieces that should protect the king.
