I think when he meant he was lonely it was like he wanted someone whom he could trust , share his deepest secrets with , someone whom he would feel totally comfortable with , someone like him . Yes he had fans , friends around him , but that's doesn't satisfy him . I know that feeling it's bad especially for him it was worst . He wanted someone to treat him because he was a person not because he was Michael Jackson . He didn't take his fans love for granted as they supported him all the time . When he said lonely he meant he wanted someone really close to him .
No, I don't think he is or was lonely. He's so many famous friends, and millions of people on this planet that love him. Thats not lonelinest. I'm the one who's lonely. He's got plenty of friends and I don't have any.
Michael said he was lonely many times, since childhood. That changed a bit when he had his children and he could be with them, when not working. When he said that he was lonely, he did not mean that he was alone, but that there was no one close to him loving, liking him for who he is as a person and not as a super star. Sure he had lots of friends, big family, fans going crazy over him, and they always wanted something from Michael, be it money (his father was asking for money), autographs, concerts, even his brothers were pressuring him sometimes in having more concerts as Jackson 5. Michael was a very giving, lovely person, which also brought in greed from people around him, famous or not. The most times when he was happy, enjoying himself, was when he spent time with his children, or other children at Neverland. I could go on and on about this - loneliness - but I think is a good point to stop.
