Confidence issues

I used to be really social, confident and carefree a couple of years ago but in recent years I've just gotten more and more quiet, shy, akward , self concious and all that. Like now I can't even answer my phone without feeling anxious and stressed. I feel like I'm still like confident and how I used to be around my close friends but I'm worried like people outside my group will judge me for how I act but idk I'm really paranoid. Any help is greatly appreciated😇💖
