Im at my wits end!!!!

I just dont know what to do. I need motivation I need something. I bought a book today regarding the GI index hopefully it will be easy to read. I want to lose 23 lbs in 10 weeks. It is just 10% of my current weight. I am not sure how to bring it all together..im not sure what to do. Im a bit depressed. I want to be slender. is that so much to ask? well apparently it is. i remember this time last year i was motivated but now im not! why. i just feel like giving up. i keep thinking when i move when i do this when i do that then i would lose the weight! well it aint happening. well i will start listening to renee again that seemed to keep me motivated. it helped me believe i can do it. ok i will try again.
