My stutter over the years

My stutter over the years I need help please, While growing up as a kid my stutter was kind of rough. I used force the letters to come out and ended up repeating the same letter until the full word came out, years later with speech therapy my problem kind of died down. Currently whenever I speak I feel a tightness in my chest and I just stop talking to stop the stutter that will come out. It would take me a few seconds in order to regain focus and speak the words I want to. I also steer away from words that I preconceive I will stutter on or to be unable to say. I'm not sure if people face something similar to what I am facing.
