Actress Amanda Seyfried wants to have children "badly" but feels like she is running out of time to start a family.

The "Ted 2" actress, who is set to celebrate her 30th birthday in December and is dating 37-year-old actor Justin Long, has been broody for two years.

"I keep feeling like my eggs are dying off. I need to get on it... I want a child. Badly. I want to be a mother, badly. That's what I feel. I've been feeling it for like, two years. I'm not ready but nobody's ready. It changes everything... so how you can ever be ready for that," Seyfried told Marie Claire magazine reports femalefirst.co.uk.

Seyfried suffers from anxiety and regularly goes to therapy to help her cope.

She said: "It's coping with life. I've been told to not talk about it, but (anxiety) is so very common. I just think, you go to your doctor about heart problems, or an eye doctor if you have an infection, you have to take care of yourself.

"Mental health is so segregated, it sucks. You don't necessarily have to have something chemically wrong with your brain to have mental health issues."
