Where's your dad? Is there anyone in your family your mom does listen to? My advice would be to learn as much as you can about stuttering. You need to become a somewhat authority on it (you already are sort of since you've been living with it your whole life). You can firmly and I mean clear and firm, tell your mom she is making your speech worse and it's hurting you. And she needs to listen because you both know she doesn't know what to do and she's panicked. (might wanna go gentler on that one). Are you Kuwaiti by chance?
