It’s getting to the point that I can’t even get an interview

I am physically not very attractive, average to below average and socially anxious but I thought I’ve been getting better with that lately. Having good interviews is always hard when you don’t have model good looks or you are unattractive and I’ve never had good experiences with them. But now stores aren’t even contacting me back when I apply like they already know I’m an ugly loser and think or something about my resume that they hate. I can’t even get an interview anymore for jobs that require basically no experience. I’m pretty cooked in this current job market and have a feeling it’s only getting worse. Even having talent at something like music which I have (I play the guitar) isn’t enough if you are not conventionally attractive or know the right people
