College

So I recently started college last week on the 15th and it was going pretty good til Friday. On Friday I missed my last class of the day cause I read my schedule wrong. I have horrible anxiety and couldn’t tell him. I tried to go by his room but he has a class. So then I was going to email him but my uncle who works and the university said to just talk to him face to face and not worry since he didn’t log in his online attendance that day. I feel horrible I feel like I’m gonna get told I’m not ready to be an adult and take the class but really it’s just my anxiety which is very bad and I don’t want the professor to be upset with me idk what to do because I’m so worried about it. Does anyone have any advice for me?
