Overcoming a spill can be tough, but it can also be a great wake-up call. Like Dog says, you can adjust things so the bike fits you better, but the back brake alone is poison in a panic situation. You need to become comfortable with stopping quickly using both brakes and the engine to slow you properly. That is only accomplished with the 3 P's.
Practice, Practice, and Practice.
Being gun shy is normal. If you love riding enough, you'll get back on that horse determined to not let it happen again.
