London: Rocker Pete Wentz credits his singer girlfriend Ashlee Simpson with helping him overcome depression.

Wentz is the bassist for the group Fall Out Boy and says he was so low once that he tried to kill himself with pills, reports thesun.co.uk. Wentz has tasted success but says it is Ashlee that keeps him emotionally balanced.

He said: "The hardest thing about depression is that it is addictive. It begins to feel uncomfortable not to be depressed. You feel guilty for feeling happy. I think I've come to terms with that over the last six months. I'm in a happier place.

"Things are so good with Ashlee. To be in a position where you're with your best friend and you can hang out with them all the time is great. I never have moments of doubt with her."
