I don't wanna restart that argument between Sheila and MJsBG but I feel like I should just say this: there are two main ways to make someone understand; you either do it politely or harshly. I think as a fellow MJ fan - as a fellow human being - you should go about things in a polite way - that is if they're not hurting you directly.
I personally feel MJsBG's pain or emotions but instead of being transformed into sadness, they take the route of anger and rebellion. I constantly attack people who undermine his fame and music based on his personal life or whatever. When he died even though I wasn't a true fan of his until later that year - I had only seen/heard Dangerous - I felt as if something had collapsed inside me. I had never felt this way before. And there are some songs which are hard to listen for example Dear Michael and One Day In Your Life and Someone In the Dark because they remind me of how difficult his life had been because of the negative publicity and his general alienation.
Having said all this, MJsBG, look, you can't always let his death consume your love for his music. If you feel like you'll cry during MITM or Jam, do so. Cry as much as you can and everything will become better. I do every time I listen to Dear Michael and slowly the hurt is turning into nostalgia - which is a positive change. I personally don't mind you saying how difficult it is for you to listen to his music. Mainly because I let out my depression in this way too. But the people around me don't like it when I tell them about my depression or my problems because they aren't theirs!
So try to move on. Or join more MJ forums and communicate your love for him and celebrate his life. Mj himself said "In a world filled with hate, we must still dare to hope. In a world filled with anger, we must still dare to comfort. In a world filled with despair, we must still dare to dream. And in a world filled with distrust, we must still dare to believe."
Make some new friends! Live your life fully! Do all the stuff you always wanted to do. Look at those who're underprivileged compared to you. And you'll soon forget all the bad stuff. You'll soon realize that life isn't so bad at all.
But till that day I said you've got to keep the faith!!
