I've also struggled with social anxiety my whole life, and it all goes back to the belief that I'm not good enough. That belief comes from my mother, who had a narcissistic personality and constantly criticized my brother and me throughout our childhood.

Obviously, if everything you do is criticized by the most important person in your life, at some point you start believing that she's right and everything you do is wrong. And if everything you do is wrong, you eventually start believing that there's something wrong with you. That you're not good enough.

I've carried this belief with me my entire life, but things have improved after spending years in therapy, moving away from my parents, facing challenges, exercising, and gathering a huge amount of evidence that I'm actually good enough. It helped. But it's hard work.
