Let me give you advice as I went through almost the exact same thing you did. I got two concussion 2 months apart last spring and I am still dealing with my symptoms because I did exactly what you did and never took a break. TAKE A BREAK! If you are an athlete and are worried abotu losing muscle, getting out of shape, being worse when you come back etc, DONT BE! It will come back to you a lot quicker than you think. It's called muscle memory. I have a friend who played football at Boston College and got cancer and couldn't workout for 6 months due to chemo. Look at him now, he just won a super bowl with the New York Giants. I tell you this because all athletes go through times when they are limited to exercising, but it is all about how determined you are to recover and when you do get to the point of full activity again, how much you want to get back what you had before.

So, take it easy, Let your brain heal, it is not a broken bone or a sprained ankle. No doctor in history has been able to tell somebody exactly when their concussion will be cured, so give it time!
