Speech stammering with anxiety. With it.

I have a stammering issue which becomes significantly worse in stressful situations, especially during meetings, or when I have to speak in front of people. Because of this, I experience intense anxiety even before such situations, and I often feel embarrassed and fearful of being judged. Due to this, I have started avoiding speaking situations and official responsibilities that require communication. This is affecting my confidence and my ability to function in my current job, which involves public interaction. At this point, I feel like I am constantly trying to escape these situations, and it is making me think of quitting my job just to avoid this stress. I want help in managing both my stammering and the anxiety associated with it.
