I'm the same. Still in my early teens too and i always get embarassed or afraid to talk to someone because of the thought of looking weird to them. I don't know what makes us think of "Having to look good" to someone or make them feel like it's just a normal conversation between normal people. It sucks. Even though recently, there is a certain thought that keeps popping up on me. "What if i die today? Wouldn't i regret not doing anything or avoiding it due to something i don't have any control to?" and the one that goes "We only got one chance on living life anyway, why don't i just give it a chance and embarass myself in front of people if that means getting to my goal?" Even by thinking of that, I still can't make myself DO IT. I just don't know. The thought of "i shouldn't put myself infront of people" and bcz of the anxiety it'll give me is much stronger than my determination to reach my goal. I just couldn't think of ways to beat it. I don't want to live my life full of regrets by time i'm old but at the same time, i hate doing anything. Because ANYTHING involves TALKING.
