Suicide is a hard topic. My mom did it. I don't talk to my father. I might be autistic or have aspbergers, and I dont understand why I wake up. I'm a robot emulating a human. I have to do weed to grt any mystery of a cosmic connection because we are strange primates. I hate my job which causes a disease of more when even after excelling in a fang job making over seven figures, I feel very little joy. I just have hope…
Given that you suspect that you are neurodivergent(you mentioned autism), please talk to a professional. Maybe figuring out exactly what makes you tick is what you need - or maybe there's something that's preventing you from feeling 'joy' (anhedonia is a classic depression sign).
Don't wait until retirement. You can certainly afford talking to a therapist (from a monetary perspective at least, time may be another matter). But just do it.
I think that 'joy' is a target that can't be reached. No matter how wonderful one's life become, we'll adapt. Joy is fleeting (but you should still experience some occasionally). Not hating having to wake up is a good first goal though. I'm also working on that part.
