I asked her to block me and... she really did. Did I mess up?

So there was this girl (16) from my school I met a month and a half ago. We started texting every day, we both liked each other. She was super interested in me. However, on November 25, she said she didn't want to be my friend anymore. I asked for the reasons and she said that it seems like I am obsessed with her. I don't understand her behaviour because even she confessed to having feelings for me.
So I tried to convince her to continue together, but she said she would decide. The next day, 26, she made up her mind not to be my friend anymore. I got anxious and insisted, and then told her I was tired of her, and also asked her to block me. I am blocked until now (for 5 days). I wonder if I screwed up everything.

Well, my plan now is to take a break. I'll try to get in touch around Christmas to apologize. Should I message her from another phone, or would I be bothering too much? She's avoiding me in school and I don't want her to think I'm stalking her, so I don't pretend to approach her too soon.
