When I got certified last year, my dad was the nervous one, he kept telling me to be careful and reminding me that diving can be dangerous (he's never dived before, so he probably has slightly exagerated ideas about it), and each time, I'd say "yes, I know", which is true, and walk out the door to go to the classes. Lucky for me he was sleeping when I left for the open water dive days or I might not have ever been able to get out the door. My mom, on the other hand, (she got certified when she was around my age (I'm 22) but doesn't dive anymore) just told me to be careful and have fun.
Every time I plan on diving, my dad reminds me again. I'm planning on doing AOW in June and I expect his concern. I'm going on my first dive trip in August and I expect even more concern then, and I kinda hope he won't be awake when I leave for the airport.
This is what parents do, they worry about their kids. Enjoy the class, your mom will enjoy the fact that you're having fun with it.
