I went to speech therapy earlier in the year as well. My stutter still fluctuates but I've learnt to accept my stutter even though I still can't stutter openly in front of others. Saying sounds like B, D, G softly and breathing correctly has helped as I used to always hold my breath in order to not stutter as much. I’m not sure if holding my breath while speaking is related to my social anxiety, but I still have to stop myself from doing it.
