I know what you mean, I stopped listening to music for a long time because I was so jealous of their ability to make the music they feel. I want so badly to make the music I know is in me that sometimes it hurts. Unfortunately, my fear of failure and self doubt keeps me from being able to really create music, even thought I want it so badly.
Oh, and just so you know, musicians have issues just like everyone else. Most of the people I ran with before this happened were musicians and it wasn't all girls and glamor. Some are constantly seeking validation through playing, some can't ever have a decent long-term relationship because they're always on the road, and some are just going completely crazy trying to manage their bands and their lives! Most people who seem like they have all the answers are just as screwed up as us, they're just better at hiding it.
