Why do I get depressed before/after going to see someone I love in concert?

It is so sad that you feel the need to compare your life to some imagined life of a celebrity. They have problems and issues in their lives to, it's just that when you see them on stage they seem so perfect and larger than life. You need to try to find joy in your life, not someone elses. Find what makes you happy and go for it. Forget celebrities, they're just people to and you're never going to feel like you compare because you think their lives are so special -- they're not. It's just the press that makes them out to be so cool or whatever. I'd stop going to concerts if it makes you feel this lousy -- that's masacistic. Do things that make you feel good and that make you feel special or empowered, stop trying to be someone you're not. You're special in your own way, and believe me, that's more than good enough!!
