My Speech problems

My Speech problems Why do I stutter so much? Sometimes I talk normally, but then I talk so fast that people can't understand me. I also stutter or can't talk when I'm in loud spaces where I can't hear myself. When I'm stressed, I tend to stutter and clutter my words more. Sometimes my sentences aren't even sentences. I am so sick of talking like this. I want to speak normally. I am not sure if this is neurological/neurodivergent or not, as I have not been diagnosed yet.
