Making Music

I've been writing songs since I was probably 6 or 7 years old. I can only remember a few of them from that far back, but there's something about songwriting that my spirit needs to express (sorry if this sounds weird!). Often, when I'm broken, I feel that the best way I can communicate with God is to sit down at the piano and write a song out of my circumstance and introspection.
I'm inspired by many things- the songs of great songwriters, God's Word, having a powerful conversation or experience, traveling, being in beautiful places in nature, being in a beautiful church or place with amazing architecture.
I really love writing music, but it's honestly been something that's pretty humbling, too. I've recently posted some of my songs that I've recorded onto my music myspace (www.myspace.com/musicjana) and it's kind of intimidating. I am still new at the whole thing of recording and helping the songs come to life and I've been insecure about it. It's honestly very scary putting my thoughts, melodies and voice out there for anyone to hear and review. I worry about how I sound and come across, and I know I don't need the approval of everyone, but I still desire that affirmation from those I'm close to- like, did this mean anything to you? Is this something I should keep doing?
Anyway, I am probably always going to keep writing, but I just wonder what God's plan is with all of it, will my songs and prayers come to life and others be blessed by them? I don't know. I just want to do what God has created me to do . . . whatever that may be . . . I'm still wondering about all of it. :)
