Stutter with anxiety... Solutions?

Stutter with anxiety... Solutions? I've had a mild stutter for a good amount of time, my dad has the same thing. I feel like my stutters are a result of my anxiety. I feel like I rehearse what I'm gonna say in my head a bunch of times and then get scared I'm going to stutter then I end up stuttering. But when the conversation is natural back and forth I don't really stutter. I was wondering if anyone is in the same situation and how they overcame this.
