I'm a girl and I like a girl. Problem. Cliche. Should I tell her? Read for more.

I've been working at this restaurant for two years and there's this girl there who caught my attention right away and has been on my mind ever since the very first day I started. I've never been attracted to a girl before, something about her is just different. I've never felt electricity course through me with just a single accidental lock of our eyes. I've hardly talked to her and I've been horribly shy this ENTIRE time to avoid doing something ridiculous on my end, when normally I am very fliratious and confident. I have no problem getting guys, and I don't mean that to sound arrogant, it's just that I've never, EVER, been nervous around someone before like I am with her. I'm leaving in two months to college and I'm 19 years old. She's 26 and has a one year old child, and a husband but from the tiny bits she had told me about him I don't feel like they have a very good relationship. It sounds ridiculous, but I feel like I love her. I've never been so infatuated with someone. I want to say something before I leave, but I am scared that it might spread to our coworkers. I don't even know what I'd say, perhaps just apologize for my complete awkwardness around her and explain why and how I was completely confused by it, and I wish her a happy life? But genuinely mean it?.....
