Yeah. You’re unlucky. We are too. Seriously just imagine, God could’ve gave you schizophrenia, which makes up 1% of the population too. **Schizophrenia!** Would you rather want that or just have a speaking disability? Another example, blindness, deafness, or anything of the sort. God could’ve took anything, but what did he choose? Your speech. He may have chosen this because if you could speak properly, then you would talk too much and have no friends (as an example.) If you could talk you could’ve done all sorts, but God, with his omniscience, prevented all that from happening. You are you, no one can change that. You are unique and beautiful in your own way. Don’t let that distract you from knowing that so many other people have problems they have to deal with. (written from a believer in God perspective)
