Yesss mine had gotten better for a a period of probably like 3 years when I was younger I am 18 almost 19 then it came back, I believe some bad experiences from when I was small brought it back because I had an experience that reminded me of that situation and brought it back if that makes sense like a very intense stutter moment as a kid something I went through made it come back very intensely causing my stutter to come back if that makes sense
