You certainly don't need surgery. What you need is the right help, therapist, and support to help you work through your underlying issues.
The problem is your unhealthy belief that you feel you are inferior and worthless. A trained anxiety disorder specialist can help you to work through your underlying beliefs/factors and make healthy behavioral change.
I used to feel just like you, but I got better once I got the right help. Social anxiety is very rarely a problem for me anymore because my thought life is much healthier and my body is less stressed and symptomatic (brain fog, memory, fatigue, etc) because I'm not worrying all the time and thinking negatively.
I'm telling you - when you think in unhealthy ways, your body RESPONDS physiologically, psychologically, and emotionally.
If you'd like more info on how to find the right help, let me know. You can recover, I can assure you. I used to be exactly like you - my anxiety disorder and depression were so deep my wife left me because she said my mental health issues were making her miserable. I understand the pain and suffering. But I also understand you can change and get better. I'll be praying for you.
