When losing feels way worse, than winning feels good?

[sweeng8]

Has anyone had this problem when losing at poker really gets you down whereas winning doesnt give you much of a reaction at all? Playing at my limits (2/4) I get really down if I have a losing session, even $100, but if I win $500 I dont really feel anything particularly good. Its like im used to the high, but still get the lows. This isnt really a huge issue, as long as im making money I can put up with varience, but I dont think im enjoying the game as much anymore because of it. It doesnt effect my game, but poker has become a chore nowadays to make money rather than playing for the pleasure of the game.
