From The Federalist:

Seeing a gun in my house, looking at it lying on my bed while it was being cleaned (why was he cleaning it on our bed?), watching someone pick it up and handle it, and handling it myself all made my guts scream. I had a very emotional reaction to that hunk of metal, even though I knew it was unloaded.

Go ahead and unlearn that by getting comfortable handling a gun. Practice picking it up with your finger alongside the frame outside the trigger guard, loading and unloading it with dummy ammo, and aiming it properly when it’s unloaded. Read this article, too.
