I'm so lost.

I dont know what to do anymore... I've been dating this girl for 4 months, who unfortunately lives in a different country. We sometimes argue a little because of trust issues, but other than that were usually fine with eachother, we'd speak all day every day, however the last argument we had was at the start of the month, she was on holiday at the time, and the argument led to her saying she wants a break from me. So for about a week or 2 after that we didn't really speak at all, I was attempting to contact her but she would just ignore me, tell me to F-off, call me stupid, she blocked/unfriended me on basically everything that we was friends on. And then about a week ago, after me trying so hard to fix things with her and to make progress, she finally added me back on Snapchat and we began to talk little bit over a few days. Whilst speaking she would sometimes say how she's really sad and upset, but would never tell me why whenever I asked, I kept asking her and told her I want to understand more and try to help her, but she wouldn't tell me and said I'm being pushy about it when I was just trying to care, then one night, about 6 days ago or something, she sent me a snap of an elevator and said she'd never been there before, I asked where she is and what she's doing, then she responded with "I need to block you again, bye". And she hasn't contacted me again since, I've been trying to send her text messages and called her but I'm getting nowhere (1)
