My (18M) Girlfriend (18F) has blocked me from everywhere.

So my girlfriend was to give her NEET (National Eligibility cum Entrance Test, essentially an entrance examination for Medical Graduation in India) exam today. From what I have heard and analysed the exam was extremely hard and tough as compared to previous years. I tried reaching out by calling her and texting her every 20 minutes. However, 20 minutes ago I realised that my messages are not delivering. I have been blocked. My number, WhatsApp and Snap has been blocked. She deleted her Insta ID so that is out of the question.

Two nights ago only she had made a very sweet love letter for me. And now she is gone. But she always used to taunt me about how she can easily leave and ghost any and everyone she wants to and simply go underground. And I have seen her do that to many of her friends. She was a mental wreck as for a few days she would be extremely happy, jolly and confident and the next week she would either be humiliating me or threatening as to how I am a bad boyfriend and that she deserves better and hotter. And that the moment she gets into college she would dump and ghost me and go for someone better.

I am thinking of going to her place this Friday as I have my own Semester exams this whole week. But should I brace myself for the fact that our 2 year long relationship is finally over ?

TLDR: My GF, who has a history of taunting and humiliating me but at the same time showing hell loads of affection on me, has blocked me from everywhere. Are we done and over or is there any hope ?
