How do i get over a girl who basically friend-zoned me but we were close?

Im 21, this girl was 22, we met at university. From the moment i met her at an event i knew she was amazing. We had the similar hobbies, played the same sports, same ethnicity.

We werent a thing, just really close friends but she knew i liked her.

In our 1.5 years of friendship we got really close. I was always there for her, she needed a hand? Im there. She had a bad day and was upset? Id cheer her up. She loved it so much and told me how much she appreciated me. She even called me her guardian angel.

I also gave her space. I even told her i liked her and when she said she appreciated it but wants to say close friends i understood.

All in all we were the closest of friends. She even asked me if I could buy her a bracelet and anklet which i did. She loved it and i even remember the smile on her face when i gave it to her at university.

Long story short, one day she goes on about how shes deactivating and blocks me, and i never hear from yer again except on small convos on instagram where i asked her whay happend and she just said she needed time alone, and that she wanted to text me, but didnt know my instagram when she did? She told me she got me a present, i never got it.

All in all i imagined giving her the world and it just really hurt because i really cared for this girl and would literally walk on broken glass for her.

Its been almost a year since i last contacted her , heard nothing except i did see her on that app called wizz.

Idk what to do
