You're right. Its how we're programmed but its not impossible. You dont need anyones approval, you're your own person. You need to disconnect yourself from this world and its "feelings". You need to break free from your "human nature" and take control of your body. This is a stuttering thread and ive dealt with it my whole life. It didn't start getting better until I stopped caring. Learn about the chakras and how youe body needs to align to function properly. Alot of us have abuse or underlying issues we dont know about or wanna deal with. Its about letting our egos go and bringing ourselves into a calm state. So yes you need to stop caring about what others think of you. While also being respectful and courteous. I still stutter and im 25. Im here to help, not be another problem in your life.
