Changing words to avoid stuttering is a very bad practice. When you avoid difficult words, your subconscious mind associates more fear with them, making you even more fearful in the future when those thoughts arise. Here's how I solved this: 1. First, try to cure your anxiety with meditation, gratitude, laughter, and other similar practices. As your anxiety decreases, you will have less fear. When your anxiety is at zero, your fear will also be at zero. 2. Pick a random number and try to say the word you stutter on. It doesn’t matter if you stutter—try with a smile. Hope it will work fine. I stuttered for 28 years, but after joining an online course i able to fully cure my stuttering. Now, I am more relaxed, happy, always looking for new friends, and have zero social anxiety and fear. I practice meditation, silent laughter, gratitude practice, and some other secret practices to cure my stuttering.
