This sentiment is true in the experiences I've had. I've made unbelievable progress at making my stutter my bitch the past 10 years, but it doesn't stop, it never stops gnawing at my mental state. Every interaction has to be meticulously planned and executed perfectly. I do not possess the luxury of free information exchange and unfortunately I'm too self aware and receptive of others to clock exactly when I'm demoted to a lower peg of suspected mental incapacity. I'm not very bothered by it anymore but it doesn't mean it's imaginary. And currently I only face difficulty pronouncing 8 or so sound combinations, my issues. People who have it worse than me are stronger than I could ever comprehend. At least my stutter is mostly a me to worked around. Meeting new people is difficult but Im lucky enough to find solace in trusting that the people I choose put energy into out the same into me, stammer and all of my other quirks included
