Do you consider your stutter a 'disability'?

Do you consider your stutter a 'disability'? I often refer to my stutter as a disability, but I've had people (who don't stutter) claim I was exaggerating. My stutter is debilitating and has ruined about every area of my life, it constantly affects in my daily life (definitiely not in a good way), I've found myself very disadvantaged in many ways (school for example) because of it. What do you think? Do you consider your stutter disabling? Of course it also depends on the intensity of one's stutter. (apologies on my english, it's not my first language)
