Professor love

TLDR I love my professor and have to leave her in 2 weeks. I feel like she doesn’t know how much I love her and I’ll miss her a lot. I’m 23 and my professor is 47

I’m really attracted to my professor. I’ve had her for three classes stating 3 years ago.

I am shy about showing affection but I’m really in love with her and I’ll miss her. The class ends in a few weeks and I want to say something to her at the end or idk like hug or something because I’ll miss her but don’t know how to approach doing that.
