My wierd stutter

My wierd stutter So my stutter is kinda weird. I usually stutter when I have to say something specific or when someone asks me a question—boom, I stutter. But sometimes, I even stutter when I’m alone. There are certain letters that are hard for me, but I can say them fine if I’m not thinking about them, don’t care, or if no one’s expecting me to say them. But the moment someone asks me to say something specific, I just freeze. Does anyone else experience this? It’s so frustrating. Anyone have tips to help me? Thanks in advance.
