It sounds exactly like stuttering. Stuttering is merely the interruption of normal speech, which you have demonstrated. An obvious fix is speech therapy, but it is costly and takes forever to get results. An easier solution is deep breathing exercises. When you know you’ll have to talk, take a deep breath in and push out your stomach. Hold this. When you have to talk, release the air and speak slowly. This will give you more fluent speech by fixing open the vocal folds. Good luck with everything. It’s a tough journey, but you’ve got this!
