When to reach out

My narcissistic mother told me to fuck off and never speak to her again and hung up the phone on me as I was walking into work on Christmas Day. We haven’t spoken since then. Do I reach out? She has given me the silent treatment my whole life, even as I was a child growing up. I’m always the one reaching out and crawling back like a lost puppy with my tail between my legs. I don’t know what to do. Advice? I feel I can’t cut her off because I’m her only family member.
