Carey, 49, admits he has attempted to take his own life on two previous occasions by overdosing on drugs, and believes it is his own experiences with suicide which enable him to relate to 38-year-old Wilson's troubles.
But he claims the best cure for depression is to talk about it more openly.
He tells Access Hollywood, "It's going to sound cold, but I wasn't reading the paper going, 'Oh, poor guy.' I was thinking, ‘I hope he (Wilson) is learning what he is supposed to be learning from this whole experience and not wasting the opportunity to learn.’
"There is a reason we want attention all the time. Living in Hollywood, you can get disconnected from everybody. You can feel like you are the only one. So you feel it, you hold it in, and you don't let it go and you don't try to find help because you think, 'Oh, man, if I tell anybody, I'm going to seem like I'm weak. I won't get a movie deal. I won't get invited to...' Whatever goes through your head."
A depressed Wilson reportedly slashed his wrists in an apparent suicide attempt at his home in Santa Monica, California, last month.
