Oh, you certainly can get over your fears. I'm living proof of that. I was afraid of dogs. I was still nervous of them (or more specifically, their barking/growling) by the time we got Max. He was a very vocal dog and helped me learn about the various canine vocality and helped kill the fear for good.K I figured either sky light or high up window.
I used to be terrified of heights, somehow I was at the top of my latter reaching upwards and prunning trees two days ago. I wonder if you can actually conquer your fears?
Sounds like you've done the same - that's awesome! Well done you.
