A painful reminder

I know it sounds too dramatic, but it’s a journey that i must take. (Drama), since August 20, 2011 i was injured during a basketball game, a grave injury if i may. It was during the game that i twisted my knee (oww!), i have twisted my ankles a couple of times but the pain when you twist your knee is far more excruciating, like 5x greater and no i am not exaggerating. Seriously now. I was having a very ,very hard time to walk, i needed crutches for 2weeks and knee support thingy, and still cant walk without the feeling of my knees twisting apart. Now im stuck with this injury for almost 2 years, i haven't played basketball since then. No more exercise thus i gained weight.. (tadaaa!) Bad thing. But right now i can walk properly, but not run as fast enough as i did before, because im still scared, every time i run i feel like my knee would eventually re injure itself. Fear is always a driving factor. And don't get me started with basketball. A month after my injury i thought it was not that serious so i tried playing just slowly, but when i tried to drive the ball into the paint it happened.. That feeling of pain shooting up from my knee and i eventually sat on the floor and rolled.. Yes i rolled. THE PAAAIIINN! After that i never played again. And the bitter part? I still haven't got it checked by a doctor or bone specialist, but for me if i want to play again i think i should shape up again, got some extra baggage here and there, in order for my knee to support my upper body and not get it injured i should get those extra baggage’s out! So.. diet?jogging?exercise? Any suggestions?
