Does anyone elses stuttering fluctuate between being perfectly fluent and not being able to speak at all?

Does anyone elses stuttering fluctuate between being perfectly fluent and not being able to speak at all? Sometimes I can speak fluently for several months. My confidence raises to its highest and I actually feel good about myself and my ability to make conversations with people. I make new friends, crack a few jokes and it feels like people are actually enjoying my presence for once. It's the best feeling in the world and makes me wonder how I ever could cope with my stutter. But it changes when one day I get stuck on a word while speaking to someone. The person I was talking to wonders what's going on and I can't help but imagine what it's like to listen to someone get stuck on a word. It snowballs, being the only thing I can think about until I loose the ability to talk to people again. This also goes on for several months until I get used to it. This is when it begins to turn around and my stutter lifts until I'm fluent again. This cycle has gone on for as long as I can remember, and it's the most annoying thing in the world for me because going from speaking fluently to not being able to speak at all is the most frustrating feeling I've ever had and it makes me hate myself.
