I feel extremely alone

I feel extremely alone I couldn't socialize properly in my teenage because of my stuttering and social anxiety, and now I'm 21 and still can't socialize. That makes me feel very lonely, especially today, I'm feeling lonely in a horrible way. It seems there's a hole in my chest, a hole that I can't fill it properly because of my disabled speech and my fear of getting caught stuttering. Do you guys feel that too? How do you deal with that monstrous loneliness?
