Stuttering preemptively

Stuttering preemptively I realize I will stutter on words which I preemptively thought I will stutter on. For instance, I wanted to say, “Mary had a low threshold for things.” In my mind before I speak, I will have the thought that I might stutter on the word “threshold”, and hence will be more aware to slow down in an attempt to avoid stuttering. But it makes it worse instead, where the thought will cause me to definitely stutter on the word “threshold”. Is there a way around this issue, or is anyone facing this issue? 😖
