How to tell my girlfriend about the struggle with the stutter

How to tell my girlfriend about the struggle with the stutter My girlfriend and I have been together for two months now and I already told her about my stutter but I don't think she understands the struggle of what I've been through. Don't get me wrong she is amazing and supporting me all the way, but she wants to know more about it. So is there maybe a video or some nice book or stories I can show her that she will fully understand the struggle?
