Asking for your heartfelt duas today, please

As-salamu alaykum. I am reaching out with a heavy heart, in need of your sincere duas for myself and my dear sister. She has been courageously battling cancer for over three years, and she is only 34 years old. These past years have been filled with immense hardship. Each time she begins a new treatment, it offers hope, only for it to stop working after a few months. Just five months ago, her pain was overwhelming. By the mercy of Allah, we were able to join a clinical trial after much effort. Alhamdulillah, she was responding beautifully, but today we received the difficult news that her condition is progressing again. As her primary caregiver, I feel utterly drained and exhausted. Every waking moment, I make dua for her healing-it is my first thought in the morning and my last prayer at night. Nothing else in my life compares to this. Over these three years, I feel I have lost a sense of myself. I have placed my career and plans for my own married future on hold, as she needs me more than anything. Who else would care for her if I did not? I would give everything I have to see her stable and healthy again. Our parents live overseas, and one of my siblings is married and lives far away. Often, it feels like it is just the two of us against this trial, and the fatigue runs deep into my soul. Tonight, I humbly ask for your powerful duas, from anyone who reads this. Jazakum Allahu khayran.
