I have a short arm, but had the same problem and was very intimidated by it. I let it sit for about 6 months before I did anything with it. I finally just loaded a throw sized top and said "oh well, what will be, will be..."! It came out pretty good! That was a few years ago.
Now I still get intimidated when I load a quilt, but it is in trying to figure out how to fit the pattern in the way I want it. I only have a depth of 5 inches to quilt in, so it is hard (for me) to "blend" it in so it doesn't just look like rows!
