Im 18. I think I have social anxiety. I cant face social situations. Also I feel some trembling of face muscles while talking close to someone. Also im afraid of looking someone and talking to him. Even in a bus or train, I feel im getting noticed everywhere. This makes me sweat more.. Also I blush very often while smiling. When my friends talk about me in a group, I cant smile, because, that smile becomes blushing.Please help me, how can I get rid of this ?please
