Theres alot you can do... Study film, read about boxing, read about your injury and PROPER STRETCHING (IE when and how)...
I'm getting an intense vibe from you that makes me think you'll jump back in too early and reinjure yourself.
But seriously dude, you need to get your head on straight. Injuries happen, its no big thing, just rehabilitate properly, and follow your physicians advice... If you're really concerned see a sports medicine specialist, a family practice DR might not fully understand the intensity behind boxing and may clear you too early.
