Don’t worry I don’t mind! First question, it can happen! But don’t worry non-stutterers won’t get a stutter. Similar to Tourretes a stutter can get worse when interacting with another stutter! And no it does not get worse when reading or learning about it! Some good stutterer YouTube channels are StammerOn, Paige White, TeaTalks, Matice Ahnjamine, and so on! And yes I do stutterers myself, moderate-severe. My siblings mock me but my parents always try to be helpful, though no one in my family stutters. My friends sometimes laughed but they changed now. And trust me, it is tiring. If it doesn’t get away, you will have to get used to it.
