take it slow

I have been overdoing it with my movements and trying to exercise... today I was sitting on the couch and suddenly i had really sharp pain shooting from my lower back down my thighs. It was so painful and I couldnt move for awhile.

I know its my fault. I have to take it slow with the exercise even though I desperately want to lose weight faster. So i just need to slow down and be more careful. I don't want to end up suffering the way I did last month... I can't afford any more time away from work or not being able to do much...
