Stodden, 55, said she is anxious about her first motherhood because of her illness, reported Us magazine.
"I suffer from depression. My depression affects my appetite, sleeping patterns and overall perspective on life. At times, I have severe insomnia and other times I find myself sleeping too much. I have feelings of hopelessness but experience many moments of absolute euphoria.
"I already love this baby so much. I just fear the thought of motherhood. It's such an overwhelming responsibility and I want to be the very best mommy that I can possibly be," she said.
"I'm working on a self-help book called 'Blonde & Blue'. It's an explicit in-depth account of my saddest, darkest moments as well as my highs ... My hope is by being painfully honest, my story can inspire others.
