GAINING ON ME

I know I have a weight problem. Lately I've been thru a slumpt with it. Most of the time I'm good getting out of the gate but never reach the finish line. My motivation is not there anymore. What does it take to get the right push? I'm not feeling the music anymore. I've been staring at my guitar for weeks on end. The only thing I think about is food . If I keep this up I'll have more health problems or worse. Why can't I get that push?
