This is why I think stuttering is the same for everyone but their condition to it is different, more or less severe in any particular moment. I was made fun of for this because on the outset everyone happens to sound differently and yet so many from different languages, cultures, sex, and so on can relate to what someone else is going through and remember it themselves.  Depending on how they are conditioned, it may sound different in the outside but the issue is the same, something deeper is interfering based on emotions or what have you.  Those that say they stutter alone may be conditioned in some aspects too but that doesn't negate the idea that the deeper issue isn't the same for us all.   What ever mechanism throws me off gives me the same exact responses as I hear from others, even if I am less severe overall or more severe in other unique aspects.  I went through all of what I heard on the discord from every which different race, gender, country of origin, etc.  I hate the scapegoat that everyone is different, that made me feel hopeless for the longest time in my teens thinking this was just my severity level and I couldn't change it.  The worst idea they offer imho I'm sorry to say! They cannot say we are all uniquely different in severity because then how can they say on the flipside that they can help.  There is no cure, sure, it is unique from our conditioning, sure, but how is it any more different beyond that, how do they know.  Doesn't all evidence point to the underlying issue being the same for others if others can relate and have gone through the same one time or another?  If we can describe how we feel and what is happening during a stutter bout, would it be totally different from someone else?  Everyone knows what a block is and feels like.   I believe we can move forward and offer ideas if we accept that we are not uniquely different person to person beyond our personal conditioning triggers.
