The realest answer is that it's gotta be a choice that comes from you, from within. But I'll see if I can offer a few ideas. 1. Locus of control. Even with your best efforts, you can't completely pick your level of fluency. Keep your attention on what you have control over, like the things you say about yourself and the choice to engage or avoid communication. 2. Perfect fluency doesn't exist, for anyone. Nobody has the right to put you below them else just because of a difference in your speech. That includes yourself, so be kind to yourself! 3. Fluency is a means to an end. The goal is to be comfortable speaking, regardless of fluency. A thought experiment sometimes helps reprioritize your thinking around your quality of life. If you woke up tomorrow and your stutter was magically gone, what would be different about your life? That might help you identify the parts of your life that are most affected by stuttering, and help you focus on getting better at those things using the speech you have rather than denying yourself.
