how do you stop stuttering (fr)

how do you stop stuttering (fr) honestly, stuttering is such a big problem, most especially when it comes to speaking- and making extraspontaneous speeches- which is what my teachers soemtimes do when they usually come up with activities that involve debating or arguing. i usually repeat a point but it doesn't do a point since the other side always wins. it's also affecting the way i read things- since when i mispronounce a word- i try to perfect it and then continue- help please 😭😭🥀
