My interpretation: I'm worried about going back to school, because I forget how to be a student. And I'm worried that I'll have to take classes over again just because I'm afraid I won't remember any of it.
Now I'm starting to get worried that this isn't what I'm supposed to be doing. I don't know if the major is right, or if it'd even matter for me to get a degree when I just want to stay home with my kids. Worry worry worry.
