If what they say is 'nothing is forever', then what makes love the exception?

My YP passed away last month. I don't know why, but I feel the grief as raw as I did back when I heard it over the phone. I'm just not ready to say goodbye. It wasn't unexpected - she was in a coma for weeks. My parents finally decided to take her off the respirator, only to have her improve miraculously. And I felt she was just waiting for me to come back. But it was a struggle, and she still left in the end. And my parents, they are already over it, going about their lives as if nothing has changed. But she is gone, and I feel abandoned. For 21 years, she had been my rock. I used to curl up next to her at night whenever I was sad. And she would always cook my favourite food before exams. And how she would sometimes ask me to buy the paper on the way back from school, but I would remember only half the time. Everything just seems so meaningless now, such that even leaving my room is a chore. I wish I could speak to her again. I wish I could tell her how I feel. That she was special, and my heart hasn't felt fully happy since.
