Would speech therapy help if I have a more "mental" stutter?

Would speech therapy help if I have a more "mental" stutter? I am fully convinced my stutter is based on my mental state and my fluency is better when I'm comfortable or confident. Since I suffered some trauma earlier this year, my stutter has gotten worse and I've been considering speech therapy. However, I wonder if speed therapy would be beneficial if my stutter is tied to my mental state/emotions. Has anyone with a anxiety based stutter had success with speech therapy?
