so, this sounds REALLY dumb, but im 14, and seemingly out of nowhere developed a stutter, idk if i had one as a kid, but nobody believes me they all think im faking it. some ask why im stuttering and get mad, others dont say anything, and i just dont know. i dont know if it sounds fake, or if its just because i randomly started stuttering, i just dont know. im pretty sure i didnt hit my head, i guess ill edit if i can remember a time recently. i used to just say ummmm and forget what i was saying a lot, and i have adhd. but if i can make it go away, i will, but if i cant, then lifes gonna suck XD
