People have noticed. No ones said anything though and I did raise my concern to a manager and another trainee manager. Neither seemed to be concerned but I'm also not sure they understand the difficulties I've faced recently. I don't want it to have an effect on my job or my customers. I would hate to not be able to pass over information or complete a call in time and risk someone's life due to my stutter. It wasn't an issue at the start but it seems to be getting more severe and I've developed some blocks too.
