A different type of social anxiety ?

Is there a term for being anxious when u see or have a conversation with people you already know? Like when you ar3 having the conversation you just cannot speak properly, kind of freeze in that moment, want to escape and just be alone for that moment. And then that makes it hard for you to have a conversation or face them in future

But that doesnt happen if you meet someone new, or if you are in a totally new setting.

I am 19 right now, and I have started noticing these things about myself and my interactions.i have noticed that I have been like even as a kid. Like I can make friends but that friendship ends when the school year ends, or a semster ends - the friendship just fades away, people gwt busy in their lives. I don't have long lasting friends or even a friend group.

This is actually frustrating sometimes because I do not really have friends left. I am doing volunteering to meet new people and I am not scared to do that. Its just that when I see someone who has seen my anxious version that I want to escape their vision.

I think learning more about this thing will help me.
