I am 16 year old. I do exactly what you are doing. i have a schoolfellow which is also a stutter. He have one quality that i love which is that he always use words that normal people (non-stutters) use. Like he stutters a lot in doing so but he don’t change the order of sentence or change the words in sentence. But on the other hand there is me who change words and i have never said the word on which i stutter too much. Let me tell you something. I have a friend his name is “Arham”. I have never called him by his name because it is so difficult for me to pronounce his name. But i am learning eventually that we have to practice and learn to pronounce the words which are too difficult for us to pronounce.
