Give yourself some time to mourn and heal, but then it's time to accept this new reality and move forward.
Also, just out of curiosity, do you have a weak, neutral, or strong grip? And by that I mean the position of your left hand (assuming you're a righty) on the club. Is your palm under the club (weak), on the side (neutral) or on top (strong)?
Just my
but I have found one of the quickest ways to fix a slice without having to figure out what's goofy with your swing is to move to a stronger grip. The more on top of the club your left hand is the easier it is to roll the clubface over. Heck, you might even start to draw the ball a little bit (which is by far the sexier ball flight, not even an opinion it's just a fact Jack)
