Fall Out Boy star Pete Wentz has credited his fiancee Ashlee Simpson and his regular therapy sessions with helping him overcome depression. The bassist recently admitted that he was once so depressed he tried to kill himself.

But Wentz is convinced that although he still battles with mental health issues, his relationship with Simpson has made him more emotionally balanced.

He says, "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."

The couple announced their engagement earlier this month after dating for two years.
