Angelina Jolie suffering from post-natal depression?

'The 33-year-old 'has been trying to control her emotions' around her older children Maddox, 7, Pax, 4, Zahara, 3, and Shiloh, 2, but 'her mood swings have been hard on the entire family,' according to the source.

'She has been staying in bed most of the time, all she does is sleep. She has little energy and has to force herself to remember to eat because she is still breast feeding.

'She cries at the drop of a hat and laughs at inappropriate times.'

'Everyone around her is hoping that she will talk to someone about how she is feeling.'
