Lady Gaga: 'I've Learned to Love My Darkness'

Lady Gaga has a bad case of homesickness. The singer might look like one big ball of energy and crazy fashion all the time, but she said she's pretty blue on the road -- and has "chronic sadness." Poor Gaga! She's working through it, though.

She said: “The lowest point is loneliness, being on the road. I have a chronic sadness that recurs. The lowest point was in Australia in May. I was overwhelmingly sad, and I didn’t know why because I had all these things to be happy about.”

Her sad moods have helped inspire her music, though, so there's at least a silver lining, we suppose: “I went to the studio and played for hours and I wrote what is going to be the greatest record of my career, a beautiful song about my father," she said. "I remember watching the mascara tears flood the ivories and I thought, ‘It’s OK to be sad.’ I’ve learned to love my darkness.”
