Kaori-sama
This is Kawaguchi Hidetoshi. This is a humble answer to the question.
“Unrelated Buddha”... first of all, it is necessary to think about what defines “unrelated,” but in general, I think it can be said that after one passes away, there will be no client (close blood relative) who will mourn one's body, and that there will be no client (close relatives) who perform memorial services.
However, in my humble opinion, I know that we should not get caught up in “unrelated” or “related” in the first place.
In Buddhism, at least most of the monks are devoting themselves to daily Buddhist practice, work, memorial services, good deeds, and altruism, hoping that all sentient beings in trouble will reach enlightenment and nirvana. Even if there is no blood relative to the client, as long as there are countless monks working with a bodhisattva heart, I hope you can think that all memorial services will be applied to sentient beings.

In particular, after reciting various sutras, this is an inflection sentence that can be read to the extent that it is safe to say, “Hopefully, with this merit, it will be applied to everything in general, and that we and sentient beings will all establish Buddhism. There are “Jikkō III: All the Buddhas, Buddha Bosatsu, and Mahahannya Haramitsu.”
In lost and suffering sentient beings, there is no distinction between being related and unrelated. It is important in Buddhism for all sentient beings to fulfill Buddhism, and eventually accumulate memorial services, good deeds, and acts of mercy and altruism to exert “merit” in order to be invited to enlightenment.
Also... Kaori is definitely not alone. Thanks to the various “relationships” of countless supports, we have been able to live our lives until now and in the future.
First, I hope you will slowly recuperate, be cured of your illness, and then little by little you will be able to look back at your future and what you want to do without being impatient.
