School starts on Wednesday and I’m afraid of failing. I haven't been back to school in years. I want to do it, but I’m scared I’ll show up and realize

I don’t know/remember as much as I thought and I’ll look stupid. I don’t want to attract too much attention to myself. I just want to learn and get the credit. The class costs a lot so I don’t want it to end up being a financial mistake. I want to get my internship next semester. I want to be good enough. I want to change my life for the better…A lot of people are counting on me and I don’t want to let them down!🥺 I’m scared!
