The whole problem is you obsessing about it, most of the time, people really don't give a f about your stuttering, theyre like : oh u stutter, ok (idgaf but alright). You are making a problem of stuttering, when everyone stutters some time. Get confident because there is nothing wrong with u. Its just part of who you are. People that are judging you, or mock you are dumb asf fr cauz u can't do anything about it, its like laughing about some dud in a wheelchair sayin : oh he can't walk hohoho OMG so funny. Laugh about their idioty. They shouldn't mean anything to u they are random stupid npc f'em. So yeah, its frustrating, you think you look stupid. But there is a HUUUUGE difference btw how u see it and how other ppl see it. Most of ppl don't even know its a thing they just think ur kind of shy, nervous or that your very peticular (idk if u can say that in Eng not my primary language) with your words if u got more of a block type of stutter. Everyone is insecure about a lot of things, don't let stuttering define how you act, its just something special about you, nothing wrong with that. And A LOT of people don't give a f at all. Ur being annoying by constantly bringing stuttering up. They don't care and neither should u
