Welcome to the hell is more like it. I take it your impediment is blocks like mine. When I was a kid and teen I had a repetitive stammer and in my adulthood it evolved into this. If I get stuck I have to literally take a huge a breath and force the word out with a huff and puff.. It's wearing me out emotionally and physically and decimated my self worth. I dread having to get out of bed in morning just thinking about who I will have to speak to today or what phone call I'll have to make. I've developed severe social anxiety because of it.
