Firstly accept you have stuttering next thing is don't give a fuck what others think and say, you just live life the way you want. Remember every now and then you will meet someone who will try to humiliate you because of that you feel pain and you will suffer, but in this part the pain is inevitable but the suffering is in our hands. Eventually the pain will subside too. The most important thing is accept that you have stuttering, they humiliate you because you think it is your weak point, everyone has a weakness, but we don't accept ours. If we accept ourselves with our strength's and weaknesses then they won't have any point to pick on us, cause we have accepted ourselves. And another important thing is try to not give a fuck what others think and say, this will help with your anxiety and confidence. A poem by Bukowski named roll the dice helped me alot with my life issues.
