I hate stuttering (not people who stutter, my problem with my stuttering/cluttering/block whatever you call it)

I hate stuttering (not people who stutter, my problem with my stuttering/cluttering/block whatever you call it) I have a problem, and I'm not saying it making it up, other people say I stutter. Anyway, yesterday was the worst. I went to Starbucks for breakfast. I don't like ordering food because of my problem. So the barista asked me what I wanted. I was there like a whole minute trying to order an iced coffee. Later at work (retail) every time a customer would ask me something I stutter every other word. That night I went to a meeting. There was a q/a discussion. When I raised my hand to answer and got picked, I start stumbling over my words, pausing for ten seconds in between every fourth or fifth word and then stumbling again. (this happens quite frequently so even someone pointed it out to me and wanted to work on my speech issues) anyone else like this? Or is this a small issue
