Drained from a lifetime of illness and learning struggles

I’ve been living with a sickness since I was little. Back then it wasn’t so bad, but over the years it’s gotten worse. I’m 24 now, and it really affects my day-to-day life. There’s no real cure for what I have. Ever since childhood, I’ve made countless duas, been to hospitals, seen so many doctors, and tried everything. When I was young, it didn’t mess with my mind too much, but of course I still wished to be healthy. After I hit 18, things got a lot harder. My illness got clearly worse, and I lost my self-confidence. I felt mentally crushed. At that age you’re meant to start building your future, planning your life, studying, working toward things. I tried going back to school, but my condition made every step so tough that I had to drop out. Then I tried finding an apprenticeship and jobs, even though my sickness makes daily stuff difficult. I searched for a while, worked somewhere for a bit, but the boss tried to cheat me on pay, so I left. Since then I’ve been lost again, trying to find a path. As a Muslim, I always held onto hope. They say Allah either grants what you ask for or gives something better later. I made dua for years - for healing, for ease, for my future. Tahajjud, dhikr, sabr… but nothing seems to get better. These last 6 years, since I was 18, nothing has improved. Not my health, not my money situation, not my confidence. I look at others and see them becoming better versions of themselves. They study, start businesses, get married, have kids, reach goals. Then I look at myself and think: “You can’t even live right. You can’t even look after yourself.” I always dreamed of having a family one day. Since I was a kid, I wanted to marry a good spouse and have children, build a future like everyone else. But now life just feels like endless pain and struggle. Nothing goes the way I hoped. Sometimes I honestly wish my life would end so I could finally rest. I’m mentally exhausted. Tired. No motivation left, no goals, only problems. I just wanted to let this out. If anyone has advice or went through something like this, I’d be thankful to hear it.
