Need advice

I met this girl at my part-time job, and got to know her name. From the very first moment I saw her, I fell in love with her instantly — she is so beautiful, truly gorgeous. At first she didn't talk to me much, but then one day we started chatting while we worked, and after that we talked more and more. Eventually she said, "Hey, let me give you my number — it'll be easier than emailing back and forth." I was so happy, and we talked for a while. But then I resigned, and I accidentally deleted and lost her number. After that, we lost contact.

I emailed her a few times asking if we could still be friends and if she could share her number again. I think I got carried away and told her multiple times that I really liked her and that I cared about her deeply — and I realise now that might have been too much, too soon. She never responded, and I really, really liked her. I just didn't know what else to do.
