Hey mate, I relate with you 100%! I'm an Account Manager working for a big Telecoms firm in the UK. I also have a stutter, I don't really stutter on words but sometimes I have really terrible speech blocks that I have to fill using 'ummm'. The other day I had a meeting with a client and one of my Sales Engineers to run them through a demonstration of our product and for some reason my confidence just dropped and I was bearly even able to say my Sales Engineers name. I was like Uhhhh Uhhhh my colleague Uhhhh *name* is on thr call with us. The demo felt so rushed because I kind of just wanted to get off the phone from feeling so humiliated. I found it so hard to describe the product to the customer or just have any casual interjection during the demo. I felt so humiliated especially as being the customers Account Manager they want someone who can communicate effectively. I wanted the earth to just open up and swallow me. I am very effective at my job and get on well with customers and I usually don't have much problems when I'm on the phone or video meetings as I'm quite use to it now but the other day really put a dent in my confidence. Sometimes I just want to have casual small talk with one of my customers and I find it so hard as it literally feels like my brain is being internally ripped inside from trying to focus on getting words out. Really does suck
