I stuttered over. every. word. during my interview

I stuttered over. every. word. during my interview Probably the same story we've seen here multiple times but I just needed to vent. Disclosed the stutter, got the disability accommodations, felt comfy, then it went to shit. I stuttered over every word and drageed a 30 min interview to 45 min and were only about aks me 7/10 questions. At one point the director looked bored and was checking his phone, email. With the exception of one question, I knew the answers, so well. I've been doing that stuff in my job for years, and amde strides in my current job. What hurts above all is this was a practice interview and not one I was seriously going for. I cannot imagine one where the stakes are higher. I hate it. I feel so incompetent.
