Living with Social Anxiety: My Symptoms and Experience

Does anyone have share my symptoms and experience with social anxiety? symptoms: squeezing arms and legs together when around people, excessive sweating only when anxious about sweating, flailing arms around, touching neck, hair and face often, tearing up, throat closing up, self conscious about style of walking and clothes, hyperaware of people looking at you and relating it back to you, coming off cold/not warm/uninterested/not genuine, odd body language, can't even say hi or wave at people, can't stand close to people (especially groups or taller people), uncontrollable shaking my experience: feeling like you can't control your body movements, can't think of anything to talk about with even friends and parents/feeling social inept, feeling like you come off negatively to people and that they don't like you or assume things about you, not able to carry out everyday interactions (talk to cashier, ask for help, jobs where you have to talk to customers unscripted or most jobs), being pretty much mute and non reactive around people
