Can you tell a teacher you miss her?

I miss my teacher and my summer class ended and since it’s college you can’t really go back and visit them my mom said that’s weird. I seriously feel so much loss I don’t know why. She was my favorite person and she helped me so much and now I can get in my veterinary nursing program which is like my dream job. I miss my friends from that class but I miss her more. Someone said I could email her and tell her that but I don’t know if she would care or not.
