Really sorry to hear about that, CC. Shoulder rehab is tough and your's will be more so, but you're tougher. It's a badge of honor to endure pain and come out the other side stronger and tougher.
For inspiration, if you haven't seen the movie Hacksaw Ridge yet, be sure to go see it. It's a terrific true story about conviction, courage and toughness under fire. I'm betting you'll come out of there quoting a line that you'll know when you hear it.
