I tore my left ACL three times in three years, and honestly don't even think about it as ever being hurt today. Rehab is important, but time.. time is key.
After the third one I gave it a full year before I skied. It took a while, but after two years I didn't even think about it while skiing. It's all mind games after a year or so. I'm a little better at tuning it out than most (hence the reason I retore it twice) but physically it's completely doable. Keep your head up and be stronger than this shit, it's not the end of the world
