Good on ya mate, same here, the mood had a huge effect, while I do stutter sometimes but it's only mild and nobody notices it (somehow). Year after year it's becoming easier to speak, although not gone, but I believe mine is within the normal limit, as even normal people can stutter purely out of confusion or fear so all good. Living life not stressing yourself about your stutter but embracing it and improving is the best kind of medicine imo.
