I've got some words of wisdom for ya. I hit a tree last winter, 11 months ago, New Years Eve to be exact. I was at Breck, easily one of the coolest places to ski EVER! Ruined my whole Colorado trip. Anyways, I tore the PCL in my left knee, the MCL and PCL in my right knee AND broke my right femur! So, moral of the story is thinking that while your life may suck, mine sucked wayyyyy worse. I was in a wheel chair for three months. I had to learn how to walk all over again. I was done skiing for the rest of the year and there's not even a chance of me skiing this year! So again, your life may suck with that torn ACL, but believe me, you'll be back and probably skiing on it in a couple months. So, make sure to think about my story and think that yours isn't that bad compared to me.
And some advice. Since you clearly love skiing, keep a positive mind through the whole thing and stay DETERMINED! The moment you lose control of your mind is when the whole healing process goes downhill. If you stay positive, do everything the therapist tells you to do and work out every single day, it's going to make the reward that much sweeter, TRUST ME!
If you're interested, check out my pics in my profile. You'll see me chilling in a bed with two casts on my legs. It's proof that my life sucked worse than yours!
Keep your head up bro, you'll be fine! Stay motivated and persevere! Good luck!
