Just remember one of the best of men, prophet Moses, had a speach impediment... so... Don't worry about it. He prayed to God to make him wise, to open his chest... you can research it... Jesus was born without a biological father, prophet Muhommad an orphan at a very young age and was one of the poorest of people all throughout his life, and there are others.... look how many billions of followers they earned (mind you, they were all on the same path, to preach Gods words and save their flock of sheep from the fire.... You'll do fine. Pray, read scripture, work on ways to gain relaxation, self peace, confidence, go to the gym as well, find one with a nice massage chair, i don't know where your from but I think Life Time Fitness & LA Fitness are the best... take magnesium, research on the benefits of magnesium, Zinc, Vitamin D, Vitamin C, and magnesium is definitely an underestimated muscle relaxer. So definitely find which one is ideal for you. Feel free to view the link below. Also go on Tictok and see what people discuss on the topic.
