I haven’t met you so can only share my personal experience. For me, I have no idea what caused my stutter. I do believe the beliefs, thoughts and what was programmed in my subconscious mind kept me stuttering for so many years. All those times that my past embarrassments from stuttering would re-play in my mind, hurt my speech. It served to reinforce the beliefs I had about my shitty speech, etc. This is deep but it’s also my #truth I give you a ton of credit because I’ve lived through it too and it’s hard! Life can get better, even though it may not seem like at times.
