I'm so hurt and angry at Allah

Assalamu alaikum. I know this might offend some, and I’m sorry if it does, but I need to say what’s been weighing on my heart. It’s been three years since my wife passed, and I can’t seem to move past it. I’m angry at Allah. I truly am. My wife had ALS (Amyotrophic Lateral Sclerosis). It started about five years ago when our youngest was only two. At first she felt tingling and weakness in her arms and legs, but she kept going to work as a banker, cooking, looking after the toddler. After scans and tests we got the diagnosis: ALS. We were devastated, but held on to faith - we believed life and death are in Allah’s hands and we made dua and hoped for a miracle. That hope didn’t change the course. A year after the diagnosis, she couldn’t walk and needed a wheelchair. Not long after, she was confined to bed. My eldest son and I became her carers. We fed her, washed her, helped her with everything. I kept praying, making dua, trying alternative remedies, and spent our savings - sold cars and electronics - until we barely had anything left but our home. Eventually she couldn’t breathe well and needed ventilators and a tracheostomy. She was on oxygen constantly, which was expensive and exhausting to manage. I would sit by her, recite Quran, cry while making dua, begging Allah for her life, but her condition worsened. Watching her fade, seeing the light leave her, was pure torture for us. One morning she took her last breath. My son and I broke down. I remember yelling at Allah in my grief, asking why my duas weren’t answered. We were shattered. Since then my faith has been shaken. For three years I haven’t been praying regularly, I haven’t touched the Quran, and I haven’t been to the masjid. I’m still angry at Allah, and I don’t know when that will ease. EDIT: Thank you for the messages, kind and otherwise. I’m not here to argue whether my anger is right or wrong. The past three years I’ve barely slept or eaten, and sometimes it feels like I can’t breathe - like drowning. Ramadan has been especially hard; it feels empty without her. I posted this as a way to get some of this pain out and try to cope. I apologize if I offended anyone - that wasn’t my intention.
