Stuttered at work

Stuttered at work I’ve recently started working a different are of my job. It was like every time I needed to ask something I had a bad stutter. I usually don’t let it bother me but being in a new position made me a little uncomfortable as I didn’t know everything yet. I don’t like asking for help but I know I need to, atleast for now. Even close to the end of my shift I asked one of the higher ups a simple question and could barely even say it. It was so embarrassing. Everyone has told me they don’t care that I stutter but the looks on people’s faces reminds me of when I was a kid unable to even say a full sentence. Some days I just wish I could forget all my regrets about my stutter and bad memories.
