I'd like to add a couple of lines. This applies not only to stuttering, in general to insults and humiliation, self-dignity infringements, etc. Remember, you must always fight for yourself. Otherwise it will lead to neurosis, which can shut you down and maybe even intensify your stuttering. Never forbid yourself to do this when you are in a rage. At the same time, keep your sanity, do not kill or maim a person. Almost any consequences of doing so are far better than accepting the will of an abuser, after which you become mentally handicapped. I say this as a person who has never fought back, even when I was openly fucked over. I don't want to pass the buck, but I was raised by my mother, so please stand up for yourself.
