Do I Have Autism? Need Help!

does this sound like autism? i feel like everyone knows how to talk and be a person but me. i don't have many friends and i get along better with teachers. my voice is quiet. i involuntarily hit things, make little noises, or curse if i think about past cringy moments. loud noises and many textures bother me. food texture especially is very important to me. i'm a "gifted kid". i'm always fidgeting. i know i can't get official diagnoses here. and idk if these are autism symptoms or not bc i've been diagnosed with social anxiety.
