Poor vocabulary when speaking.

Poor vocabulary when speaking. I have a decent vocabulary when I'm writing, but I feel like my stutter has ruined my speaking vocabulary as there are times where I'm a nervous wreck so I find it difficult to express my thoughts articulately. So during conversations, there's lots of instances where I'm literally speechless because I don't know what to say. It's like I'm thinking so much about my stutter, that I forget words and lose my train of thoughts. I sound like a 5 year old speaking and it's killing me. I graduated last year and I'm struggling to land a web developer job because I'm afraid to speak and call companies. **For those who a big vocabulary, how do you manage to speak eloquently even with a stutter? ❤**
