This isn’t stress, it’s breakup but I need help

We dated for about a month, we never argued, got each other gifts, always said goodnight and good morning, always kind, all except one of her friends liked me and wanted us to date forever. But this Monday, she texted me in the middle of school saying she wanted to break up. And I know this is bad, but I panicked and blocked and deleted her contact, and unfollowed all her ***’s. And I wish I hadn’t done it. Because I would be nearly this sad and I would have been able to let go. She gave me the opportunity to break up but still be friends. I regret not taking it. She’s the only one who understands me, and before we dated, we would always talk. And she would always stick up for me as I would her. She went into more detail a couple hours after we broke up, she said she still loves me and doesn’t wanna be in a relationship, and said we weren’t meant to be at the moment but maybe we could try again in the future. But next thing I know my friend who’s been friends with her told me she already likes a guy and there in the talking stage. I still have hope she will want to come back. I’ve been crying these 2 days without her I feel drained.
