Yes! I struggled in university because of this too.. I was under so much stress worrying about presentations and speaking in class that it really took a hit to my ability to retain information. Most of my childhood and adolescence is blacked out which is a sign of trauma; I feel that stuttering is a low grade reoccurring trauma for me. My brain has been stuck in ‘fight, flight or freeze’ mode for most of my life. It’s something I really have been focusing on trying to manage.
