Isn't it possible to share something with your older sister? I'm sure your older sister is also filled with the desire to share it with you. Isn't this the best memorial service for ancestors and deceased mothers? They're sisters, so I think we can understand each other even if a lot of things happen along the way. Isn't that Ni's mother's filial piety? Why don't you put up with it and apologize if you're sorry, older sister? Both your ancestors and your mother will be delighted. I can't seem to think that the reason you were consulted here in this way is that kind of relationship. “Be nice with your sister!!” I mean. Are there any more memorial services than that?
I don't know why they got into a fight. But rather than living backwards, how about starting a new parent-child and sister relationship for the future?
It seems that the meaning is different from the original meaning of “memorial service” in Buddhism. A memorial service refers to sincerely offering offerings such as incense, flowers, lights, food and drink, etc. to Buddha, Bodhisattva, etc. In Japanese folk religion, memorial services for the dead and ancestors are particularly often called memorial services, but derived from now on, they are also widely called memorial services in the sense of dealing with the dead regardless of Buddhism. Originally, a memorial service is an act of thanking the Buddha for teaching and for having a “relationship” with a monk, but it has the meaning of rejoicing at the “relationship” that we have made use of in this way.
This is a memorial service if you appreciate the fact that it has various relationships and relationships with life.
When ancestors or Mizuko are the target of memorial services, they are called “ancestral spirits” or “Mizuko spirits” as vengeful spirits that act as “haunted spirits.” A memorial service is “respecting,” “praying,” and “receiving with respect.”
It means something like that. A memorial service for your ancestors and mother is to thank yourself for who you are now being kept alive by your ancestors and mother and do your best to survive.
I sincerely wish you all the best.

Thank you so much for telling me something that is hard to say. There are various problems hidden in that family home, aren't there? I believe that reflection = awareness and appreciation are basic in Buddhism, and from that standpoint, you have taken sufficient care of yourself, and you are forgiven and loved by the Buddha, your ancestors, and your mother.
There is enough memorial service for being thanked every day at home.
I wish everyone in the family happiness.
