Hala Aboody, I'm a fellow arab who stutters too. The fact that you were forced into speech therapy as a kid and taught to try speech techniques that don't work sucks major ass. Then add to that that your twin and cousin where bonding while you were being told to do speech excercises (as if that they will "heal" your Stutter) and that the "cure" is in your hands but maybe you're not practicing enough just adds salt to the injury. I'm glad to hear that your brother got healed, and i want to tell you that the way to heal your Stutter is changing your outlook on it which is definitely easier said than done! It is hard, but i think if you hate it, and you want to stop it from negatively affecting your life then there is an inner will for change and i think that that could be your fuel. As for bonding with your brother I want you to know that as you both grow you will probably become friends and rediscover eachother again. I know that it sucks feeling like you and your twin are not friends rn but know that you are still young and you'll probably become friends later on. I don't know how much you talk to your family or your twin about your Stutter, but one way of bonding is sharing with them how hard it is on you, and telling them that you don't want their opinions you just want them to listen. I feel with stuttering it makes us feel alone, especially if no one in our families understands how it makes us feel. And what makes it even worse is that sometimes when they're doing something thinking that they're helping us, they actually aren't and are making the situation worse. I feel if you start talking with your twin about how it makes you feel being a Stutterer or someone in your family that you feel safe around i think that'll be helpful. If possible i suggest going to the National Stuttering Association (NSA) Conference happening in Los Angeles during July 2022, its a conference where people who Stutter from all over the world go to, and it feels like one big family where people are friendly and know exactly what it feels like. I hope this message helps in any way, and know that if you ever want to talk to an arab/ saudi that understands feel free to contact me.
