Feeling low but unable to understand why

So context. M33 lives with partner M55. Our life is what I would say pretty dam good from a distance.

Nice house nice cars. Comfortable money wise

Both self employed. Lots of trips in our camper. Holidays abroad. Nice area. Regular friends activities. Stable familys. It all seems very perfect from the past iv come from...

However I cant help falling low last few weeks which gets ever worse. Lost motivation to work. Lost motivation todo anything.

I just wanna run away and hide and never exist.

I asked chat gpt for advice and it thinks im experiencing burn out. My main problem is since I was 14 iv never wanted to live. I like dont want to kill myself but very happy to just die. I am happy if I got cancer or summin else. An just naturally died. Iv never enjoyed the fact we work we experience life and we die... after experiencing alot in life some amazing moments some shit moments at 33 now im like ok life done can I jump off this ship now? Im done. Not depressed just done with life. But im told im depressed. Depressed about what people would love the life i currently live and iv enjoyed it but now im like can I get off this bus now?

Am I the only one who feels ready to die?
