When this life feels too heavy and only the promise of Jannah brings peace

SubhanAllah, I’ve been holding onto the verse: 'And indeed, the Hereafter is better for you than the present life.' For the past year, my child has been dealing with health challenges, and two months ago, my father passed away-may Allah have mercy on him-after complications with medication. At this point, thinking about the akhirah is the only thing keeping me grounded. Dunya feels so empty. I’m utterly drained and broken inside. I turn to the Quran and tears just flow; anytime I’m alone, I cry. These tests feel never-ending. I’ll carry the grief of losing my father every single day for the rest of my life. My children will grow up, and I fear I’ll look back and feel I missed the joys of motherhood because of these struggles. It used to be anxiety, but now it’s just this deep sadness that this is my qadr. And I know, I know, others have it harder or easier-this is what Allah decreed for me-but it’s so, so hard. I was always hopeful before my father’s passing, telling myself, 'It will get better, inshaAllah.' He said something a few months before he left: 'It’s over for me; I’ll never be the same again.' Now I wonder, is that true for me too? If I live another 40 years, is it just more heartache? My only hope now is in Allah’s mercy and the beauty of the afterlife, alhamdulillah.
