Reasons for stuttering

Reasons for stuttering Hi guys! I am wondering if anyone has the same issue as me in regards to stuttering Every time I stutter it is ALWAYS when I know what I am going to say, like I can blabber on for hours about random stuff but as soon as I know what I’m going to say and have thought about it I just always stutter. Same happens if I read aloud from a book, because I know what I have to say all I do is stutter
