Is this a trial from Allah?

Assalamu alaikum. I'm 24 and was raised in a Muslim home. I attended Arabic school, but I wasn't consistent with my prayers and I've committed many sins. Last July I became seriously ill and since then I've been dealing with ongoing medical problems. This hardship pushed me back toward the right path. I see it as a blessing in some ways, and I want to dedicate my life to Allah and serve others. But the illness is so bad that I can barely do anything besides going to the masjid when I can and listening to the Quran, because my symptoms are really severe. I don't mean to complain, but I keep wondering if this is a kind of punishment. I spent much of my life without thinking about Allah, and now I do. Maybe He is reminding me who is in charge and that I left things too late? I tend to be very sensitive and overthink, so I'm constantly worried something will happen to my family, which causes me huge stress. I regret the time I wasted, and I'm scared of dying like this with so many missed prayers and fearful that I haven't fulfilled my responsibility as an older brother in faith. This feels like the hardest trial of my life and I fear it might take my life more than the illness itself. Please pray that Allah forgives me. I feel like I've failed in my mission and I'm really sad and feel worthless.
