Stutter getting worse for no reason

Stutter getting worse for no reason I’m a 19F in university My stutter usually gets worse when I’m nervous but even when I’m not and talking to friends and stuff it gets worse and it’s like the words just can’t come out usually it’s more of me repeating word sounds I guess. I have no reason for it and I talk a lot for work as an orientation leader so I really need to fix this. Also when I make phone calls even though um not nervous the words don’t come out and I can hear it in their tone that they are aggravated with it.It’s like I just can make the words come out. Has anyone else experienced this or know ideas on how to fix it?
