Vanessa Lachey talks about battling 'baby blues'

New mom Vanessa Lachey says she was excited to have a baby, but two weeks after giving birth to her son Camden, her mood abruptly shifted.

“I felt lost, unloved, alone and at my wits end. It’s weird, too, because I have an amazing and supportive husband, his loving family and wonderful friends. But at that moment … I felt like NO ONE understood me,” she wrote on her blog .

Lachey is married to singer and Cincinnati native, Nick Lachey. Vanessa Lachey calls the way she felt "debilitating."

She wrote, "I was feeding Camden and crying my eyes out. I felt like I had officially come undone.”

According to a study out of Northwestern University, one in 10 new moms may experience postpartum obsessive compulsive disorder.

There is a difference between postpartum depression and "baby blues." The Mayo Clinic  says baby blues last a few days to two weeks. It says postpartum depression, "may appear to be the baby blues at first, but the signs and symptoms are more intense and longer lasting, eventually interfering with your ability to care for your baby and handle other daily tasks."

There are several maternal depression support groups. Cincinnati Children's Hospital has compiled a list,  you can find it HERE .
