Please Keep My Mother in Your Duas - Need Honest Thoughts

As-salaam alaikum everyone, I need your honest opinions. My mum has been diagnosed with stage 4, triple negative metastatic cancer. The doctors tried chemo but eventually stopped because it wasn’t helping, and they even said she might not make it to Christmas. This whole ordeal has pushed me closer to Allah (SWT). I’ve been asking for shifa in every prayer and have spent nights in tahajjud crying and pleading for her recovery (Alhamdulillah for the ability to turn to Allah). I need you all to be bluntly honest with me: am I just in denial about the likelihood of her passing, or is it reasonable for me to keep asking Allah (SWT), the Shafi, for a miracle and complete shifa for my mother? The cancer has spread to her neck, one leg, kidney, lungs and spine. I know the odds look bleak, but I truly feel certain that Allah (SWT) can accept my duas and restore her health. The rest of the family talks like they’ve already accepted her death, and that makes me question whether I’m fooling myself. We did experience what we called a miracle before. Years ago, after my brother passed away, my mother was devastated and felt she couldn’t have more children. A year later, her brother was blessed with a son, and a year after that I was born - she calls me her “miracle baby.” Because of that, I keep hoping Allah (SWT) can grant another miracle now and heal her. Please be honest: am I being delusional, or is there still a chance my mother could overcome this without active treatment right now? Either way, I would really appreciate you keeping her in your duas. Jazakum Allahu khayran.
