VIDEO : Lady Gaga: 'I've Suffered Through Depression and Anxiety My Entire Life'

Underneath a seemingly seamless veneer, Lady Gaga admits she's faced a life-long battle.  "I've suffered through depression and anxiety my entire life," she said in the November issue of Billboard.   The multi-platinum Grammy winner has been a longtime activist, championing for the LGBT community and launching the Born This Way Foundation in support "of the wellness of young people." "I just want these kids to know that that depth that they feel as human beings is normal. "If I need to get the president's attention -- whatever I have to do? I'll do it."
