If you WANT to do better, but are unable to, that's not laziness. Laziness, at least as I see it, is more like "I could do more, but I don't want to, so I won't."

I also don't think framing any difficulty as "being lazy" or "spoiled" is helpful, especially if you're directing that at yourself. Even if it were true (which sounds unlikely to me!) there's no actionable step to fix being lazy, so it's worth ruling out the other potential causes before you write yourself off like that.

So the useful thing to do, and the one that is most kind to yourself, is assume you are not just lazy. You are having some kind of struggle, but let's take "lazy" off the table for now.

Others here have mentioned ADHD, anxiety, burnout, sleep apnea, or depression. These can definitely all lead to the kinds of symptoms you're experiencing, and it's worth talking to a doctor and a therapist to figure out what could be causing this.
