If you have a stutter your gonna stutter at times, sadly not much you can do about it other than just let it happen and move on. Try not to dwell on it too much because most people don’t care and will forget about it straight away. I also do sometimes thing my life would be better without a stutter but I don’t think I’d have lived the life I live now without a stutter or met a lot of people I’ve met so far in my life.
