I did develop psychological reasoning to the some degree, how ever these past days I started repressing any understanding for it... Not to mention how confidence as well as inferiority is strongly connected with my stuttering... As I get overwhelmed with issues and social problems I also degrade in my speech, yes... And I guess that to some level people around me who constantly do harmful stuff to me have effect on me as well which I can't fix in any way really... But thanks on proposing that, maybe I will start exploring the topic a bit again (sorry for the long response)
