"Apart from the beatings from my parents which is something 99.99% of parents do" Mate, no, this isn't okay, no parent should act like this it is unacceptable, and this can cause trauma for my opinion, and story with truck really sounds scary, especially when you were only 4 years old, stuttering is a very complicated disorder, no one knows how people get it, it can be genetic tho, you can learn your family tree and found out maybe that's why you have, of course i realise that you probably don't care why you have it, you wanna get rid of it, but maybe it will help you, as about how to get rid of this, let's think about it this way, when we sing, when we talk alone with ourselves, we don't stutter (the majority of us) which means that it's a psychological problem, right? so, the only way to get rid of it, or relief it, is by changing the way you think, i know it sounds cliche, but it's true, it's a very hard task, but it's achievable, you can read some books about it, here is one [https://www.stutteringhelp.org/Portals/English/book0012\_11th\_ed.pdf](https://www.stutteringhelp.org/Portals/English/book0012_11th_ed.pdf) i know, you probably don't believe in it, but nothing will hurt if you try it out, right?
