My Girl just broke up with me.

It’s been a whole month since me and her started talking. Things were going great. She told me she liked me first. Anyway yesterday she told me she was ready to be my girlfriend. So I asked her and she agreed. 2 hours later she texts me saying that she wants to focus on school and doesn’t think we should see or talk anymore. I feel very heart broken right now and don’t feel like dating again. I’m just scared to get my heart broken. What do I do to move on? How do I move on? I resume the semester next week and I have to be stress free.
