Lady Gaga suffers from chronic depression

British pop star Lady Gaga Lady says she suffers from "chronic sadness".

The singer said she struggles to cope with homesickness while on the road for tours, but has now learned to accept her "darkness".

"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," she said.
