First off
Lots of us have been where you are. I sure have. And yes, it's dead scary. But you know what? You decided to make a change. You decided to come here and talk to people and admit that you need some support to get through this.
You'll find that support here. Join some threads. Post whenever you need to. Maybe start a free blog on this site. Trust me, it helps. I kept slipping up until I joined this site. It's been fantastic. Not one slip up since I joined.
In short, you
can do this. And all of us here will help you get to your goal.
