Zeta-Jones, who revealed in April 2011 that she had checked herself into a mental facility to ease her struggle, added:
"Everyone has things going on and we deal with them the best we can. We can't jump from the rooftops shouting, 'I have this, look at me. Victim.' No, we all have issues in life. I'm really happy that I have great friends, great support and that's all I can do."
