Giving space

I (21M) began talking to this girl I met on tinder and we hit it off immediately. This is the first time I’ve felt like this since my last break up so I was so excited. It had been going well for about a week and a half (even got to the point of exchanging nudes, etc.) but we couldn’t meet up for obvious quarantine reasons. Then 3 days ago she tells me she had just broke up with someone she was seeing for 6 months a couple weeks before we started talking. Then she stopped replying to my texts two days ago. I texted her yesterday essentially asking if she was over us talking. She replied saying it has nothing to do with me and she needs to deal with it on her own and to please give her space. I felt like the text had angry subtext so I felt like I had pushed too far even off one text. Haven’t tried to contact her today at all but I’m just really worried that she won’t get back in contact with me. I really liked this girl and to have this happen has really messed with my mood. Am I just overthinking or should I just accept that this might just be a lost cause?
