I want to reconnect with a friend because we were best friends in elementary and middle school but grew apart in high school. I miss her.

But, she graduated from a very good college and is now working as a maternity doctor. I am unemployed and quit college due to anxiety. 

I’m scared I’m not smart or successful enough to be her friend anymore. I don’t want to sound dumb to her. The things I’m into seem so unimportant compared to what she’s doing in her life. I don’t want to bore her or come off as childish, and I don’t want to sound ignorant if I don’t understand what she’s talking about.
