In an interview with Good Morning America, Michael disclosed that his rise to fame in his 20s coincided with private turmoil.
Speaking about the loss of partner Anselmo Feleppa, he said: "It was a terribly depressing time. I had my very first relationship at 27 because I really had not actually come to terms with my sexuality until I was 24.
"I lost my partner to HIV then it took about three years to grieve, then after that I lost my mother. I felt almost like I was cursed.
"The only thing that got me through it was my music. It survived. I wrote very, very little, but the little I wrote did well and kept my head above water. It was depression and shock which just went on for years."
The 'Careless Whisper' singer is currently nearing the end of a seven-week US tour, with dates in six more cities - including Philadelphia, Boston and Washington – still to come.
