Social anxiety is getting so much worse ..I don’t understand this

I was never super confident or talkative. But I have developed social anxiety now. In the past, I could make conversations easily on a wide range of topics. I literally can’t talk freely to anyone other than my family. I feel like everyone is constantly judging me. I can’t make small talks. And when I must make them, I feel my body tightening. My body language is that of a person who thinks they’re burden on earth. Droopy shoulders, face down, over apologizing. That feeling is crushing me. I am pretty sure, I am called a weirdo. My voice shakes when I meet new people. And yesterday in a meeting I blanked out even if I prepared well for this. On paper, I am educated woman with good career. But this social part feels like I can’t do it at all. I am so afraid of everyone all the time. Usually, you start to care less when you are past a certain age. In my case, it’s the opposite. I feel like I’m disappearing in my own shell. Could this be related to changing hormones? I don’t know what is causing this.
