Would you call it abandonment?

was diagnosed with borderline personality disorder 2 years ago. A couple of days ago, I had a vision of an old memory from my childhood. Like i just remembered the day my nanny told me that she was not going to take care of me again. I was around 5-7 years old. And i remember that horrible pain that she was leaving me. I had tears in my eyes and she asked if i were crying and i remember telling her that i wasnt crying. Now do you think that means i was abondoned in my childhood. She was so close to me.
