Just please please please be careful. A torn ACL takes a deceptively long time to heal. It depends on the severity, but you can be out for a year with that kind of injury. I know it really sucks, but if you re-injure it, you could be out even longer. I say listen to the doc and do what you feel you're capable of, but don't push it.
I had a friend who played college football at Purdue. He was the kicker and tore his ACL. He came back, against recommendations, after 4 months and ruined his leg. Lost his scholarship and everything. Not that you have that kind of stuff at stake, but you get the idea.
