Years? If it's still bothering you, you're not desensitized to it. You're anything but.
I'll give an example: I was severely abused by my father when I was a child. The fact that I can get through that sentence without being emotionally triggered in anyway, means I'm desensitized by it. Or at least my own abuse, if anyone was to try abusing anyone I cared about I'd rip their head off with my teeth and claws, without a second thought, so I'm not so desensitized to it that I don't empathize.
