Don't be discouraged. Binding is so hard at first, but you're going to laugh at how easy it is once you master it.
I use a variety of techniques I picked up through tutorials and books. Some of those tutorials went way over my head. Here are some links that helped me and my hard head:

I cut most of my binding 2.25" and use a 1/4" seam allowance. I always use my walking foot to attach the binding. It makes everything feed evenly. To get those mitered corners, stop 1/4" from the edge and pivot your quilt. You don't have to snip the threads or anything. Just fold back the binding lining up all edges and continue sewing. Joining the ends diagonally was something I didn't master until recently. It makes hand sewing the binding to the backing much easier. No lumps!
Good luck, I know you can do it!
