Highly recommend she gets plugged into a stuttering community. It would be very hard to convince her to do this. If you don't have the patience to meet her where she is at, maybe it would be better for her to find support somewhere else. And you can move on and not think about it anymore. I know it's frustrating to watch the person you love become a shell of themselves. There are SO MANY parents of people who stutter who experience this. But you cannot do the work for them. They need to change on their own. And if you're not able to support that and make space for the fact that it's going to be extremely frustrating for you, that's ok, but you need to let go. Trying to pressure her when she's not ready and then getting increasingly frustrated with her is probably only gonna make things worse. What you're dealing with looks a lot more like complex trauma, which can develop in people who stutter due to responses that they get from others around them. It could also have started as a developed due to the incident that caused her stutter (a bigger trauma), and then is playing out in this particular way. Instead of seeing her as a stutterer, realize that she is experiencing trauma. That doesn't mean somebody sits where they are and let it destroy their life, but it does mean that the people around them need to be incredibly patient and kind and change the way they're seeing the situation. You're never going to know the person she was before that accident in the same way. You need to let go of the belief that she can completely overcome her trauma if she just tried hard. I know it is painful. And I know it is frustrating. But taking that frustration out on her is only going to make it that much harder for her to develop confidence and heal.
