I want to talk normally

I want to talk normally So I started to stutter not long ago. It came out of no where, and it's bc of my adhd. The thoughts in my head are going fast and my mouth can't keep up. I really wanna speak normally, sometimes I can't even talk bc the words won't come out and I need to use a different phrase or just change the topic of the conversation. It's really frustrating bc I wanna do public speaking one day but I just can't bc I can't seem to express myself how I want when I speak. Does someone have any idea what to do?
