There is a reason why people are drawn to- and go in the groups that share many traits with them. Try not fitting in to the world of non-stammers; instead find or construct a group of stammers or speech disabled people. You cant find sympathy or free yourself of judgement otherwise (unless you have no group at all). Naturally this is no easy task since most of us hide away in our own corner, but if you are willing to try; go for it.
