First of all its a natural feeling , however you have to accept it. I personally make fun of myself all the time whether internally or when im around people. It s a weird mechanism people tend to react and say oh no you re fine blablabla. Stuttering should push you toward being good at work or school and create situations where people will need your help and expertise/favors. That will be your power to get back at the one who try to humiliate you.
