Stuttering again suddenly after 14 years

Stuttering again suddenly after 14 years Hi! I stuttered as a kid, in particular I had the difficulty to initiate speech, but it went away by itself gradually as I grew up. However, I had had very stressful life for the last 2 years and it was in particular bad these months, and eventually I temporarily moved to a different country few days ago. Today was my first day of school here and... I started stuttering just like when I was a kid. It was a weird, long forgotten feeling. It never happened to me over all these years. Is it normal? Should I be concerned about my neurological health?
