I don't want to do exercises again. I don't

I don't want to do exercises again. I don't I've been doing so good but my mom has told me I've been stuttering again recently. I've been letting my mouth speak first more than my words, but I recognize that I just have to relax and let it flow. I usually think of musical notes to help with this, I'm trying to communicate with her that it happens sometimes and I can get back to it but it's like every time I don't agree it's talkback. I just want to say how I feel why can't I express that? She just tells me I have to do it again so it'll help me, and if you've been doing more recently you have to do it so it doesn't keep progressing the way it does. It just happens sometimes when I don't focus. I just don't want to do those exercises again I hate them, god I hate them, I don't want to feel like I'm going back to square 1. Am I just being stubborn?
