Dolly Parton says songwriting is better than seeing a shrink. She told “CMT,” her guitar is like her best friend and her songs are like her therapy. She adds, “If I had to give up everything else, if people said you can only do one thing, I’d just write. I’d say, ‘Well then, I’ll just be a songwriter.’ Because that’s how I express myself. That’s my time with God.” Parton’s new album “Pure and Simple” was out on Friday.
