OP, one thing I forgotten to mention in my reply post to you, and I feel is quite important. I do this as well. On the days where you are feeling stressed about your stuttering and you are thinking and feeling on how am I going to get through this day? Instead of viewing the entire day break the day up into smaller sections of time. For example if I can get through the next let’s say 30 minutes. Then when you do see it as an accomplishment and give yourself a pat on the back. What is happening psychologically is your training your conditioning yourself that yes I stutter and it sucks right now, but I can overcome the negative feelings I have about me being a person who stutters to a person who has gained control of one’s stutter and the stutter does not control you. At the end will you still be stuttering yes, but with a whole different outlook and attitude OP.
