Friendship problem

Okay. So i had a friend i thought she was my only friend. But after some time she started ignoring me. But still we would talk. Anyway. After we graduated from medical school, we started working in the same hospital for some days we were talking and hanging out, and i would go out of my way to help her in any way i can, one day we were sitting and i jokingly asked her about the boy she liked, we used to share almost everything atleast i would share everything with her, anyway i asked her about that boy, and she was okay with it. Then we went home and i messaged her jokingly asking her to show me the picture i was just teasing her. She said i was interfering too much in her life, i apologized but she started ignoring me wouldn't answer my texts or calls, i apologized to her many times more than 20 times she still ignored me. And one she blocked me on all social media including whatsapp. I still apologized to her using my brother's number and my mother's number she then told me to stay away and i should stop bothering her so i did then we started working in the same ward. So then again i trid to apologize to her she told me to stay away. I even tried to wish her on her birthday. And as an apology made a portrait of her which took me 3 days. But she didn't even accept my gift she didn't even ask me what it was. She was too embarrassed to talk to me and wouldn't even wanna talk to me. Our rotation is gonna end in 1 month should i try to apologize once more even though she has told me to stay away to not talk to her and even warned me that she would complain about me if i try talking to her. Should i apologize to her again.
