Congratulations! It will get easier as you do it. I've been commuting for about a month now, and I'm much more comfortable riding around in traffic than I was at the beginning. Also, if there are parts of your route you don't like, play around with it a bit. On a bike, longer is not necessarily a bad word. When I first started, the route I chose had quite a scary intersection in the middle. I did a little research (and watched the way some other cyclists we going) and discovered that if I veer off by about 8 blocks, it was *MUCH* safer. So even though it's a bit out of my way, I take that route every day - much better!

Good luck!
