I'm not sure what you mean by the last sentence. My English is not good. You sound sad. You will be okay. It took me two years longer to become a nurse. I repeated years. I'm a rather wise and very happy nurse now. If you screw up tomorrow, it's not because of you stuttering so much. They will have to accept your stutter and will want to accept your stutter. In the end you will be okay. Believe me. Lots of best wishes for you my precious stranger.
