Someone advice please?

So I moved after I graduated to come be an addictions counselor. I have to work with groups. Problem is I have never done this before. I came straight out of college no internship no nothing. I’m fresh. I’m scared they’re gonna give up on me. I know I can do it but I have to do it in a fashionable time. I’m scared they don’t believe in me. I think I can do it if I try but I m awkward and socially anxious. I’ve improved a lot. And I can talk to people I just feel in this form of my job I need to feel like no doubt go do it. That’s stupid I know but I don’t wanna give up. How was it for everyone else after grad,
Someone advice please?
