If money and fame are a problem, you can give the money away and stop acting and/or singing. No one is forcing anyone else to be a celebrity (for the most part).
I would say I have no sympathy, but that would require me to care enough to actually decide one way or another whether to feel sympathy. Celebrities are normal in that their problems mean nothing more to me than anyone else's problems. Unless the celebrity is my dad or my girlfriend or someone else in my life, why should it matter to me? Or to anyone?
