Im so lonely !!

Im so lonely !! Im 19 already , about to turn 20 , and i havent been in any kind of close relationship , i literally have zero close friends. Im not naturally like that. I wanna go out , meet people, socialize , have fun , but this anxiety related to stutter is holding me back. Its like im a extrovert stuck inside an introverts body. I have been so alone lately , that im starting to feel sick cuz of it. I need help ! Has someone else felt this for so long , and in the end you cant just take it anymore?
