Good news is that anything can be an acquired taste! Maybe try mixing it a bit in your favorite chicken and pork recipes. Grilling is tricky with rabbits because it gets dry. If you rub with a little oil (I use olive oil and seasoning) to hold in some moisture, get a good sear first and then wrap it in foil to finish cooking slowly it turns out much juicier than just grilling or not using oil (or bacon, some kind of fat).
As for feeling like a psycho killer, we would be worried about you if you were just killing for fun with no reason and enjoyed it. The fact that you don't enjoy it and are only doing it as a means to an end, well, that pretty much wipes you of the psycho killer list. I find spending a moment petting and thanking my rabbits and God for the nourishment they will provide my family eases the guilt a little, but I still use a pellet gun because it is a little more "hands off" than other methods.
Just try using rabbit in recipes you LOVE and I'm sure you will find at least a couple of dishes you come to enjoy. Bless you for raising rabbits for meat for such noble reasons and being willing to stick with it.
