I want to know why my daughter committed suicide

I read your question.
I think it was really difficult. I offer my condolences.
There are theories about suicide, so please see my answers below.

I think there are pros and cons to the act of searching for the reason the daughter died, but since the dead exist as dead people don't let the living ones weather, I don't think it's unequivocally bad.
However, if that act is not a positive act of trying to understand your daughter, and you use it as fuel for blaming and judging yourself, it is better to stop it immediately. Not forgetting is one thing and judging yourself is quite another.

People are required to die from the time they are born. As long as that is the case, I don't think we should be unhappy due to lack of family no matter how we die.
What did you learn from your daughter's death? The presence of people is irreplaceable. It's fragile and ephemeral. It must have made me keenly aware that it does not exist unconditionally forever. You should keep an eye on any minor changes and enjoy this moment with your family to your heart's content so that you can pay attention.

Please live your life in a way that makes the most of what you have experienced. It means making the most of my daughter's death.

I read it.
Your daughter passed away suddenly, and you are in deep sorrow and regret. I don't think it's unreasonable for you to have so many problems.
I sincerely understand your feelings.

I sincerely ask the Buddha so that my daughter is led by the Buddha and is born under the Buddha so that she can be more peaceful and at ease from the bottom of my heart, and I will be offering a memorial service for my daughter from the bottom of my heart.
Namu Amida Buddha Namu Amidabutsu

My daughter is always led by the Buddha, saved from all suffering, and now she will be born under the Buddha and will feel at ease. And you will attain Buddhism peacefully with a happy heart.
And from now on, you will feel at ease with the Buddha, your ancestors, and close people who have passed away before, and they will gently watch over you and everyone.

Feelings of sadness and deep regret probably won't go away, but please put your hands on the Buddha and her daughter and pass them on.
The Buddha and her daughter will always accept all of your feelings. And they protect and support you so that they gently surround you and everyone.

It may not be easy to understand why your daughter passed away. I think I was driven into great suffering due to a mental illness.
Nonetheless, my daughter was able to live through that life very hard. I was blessed with relationships with you and everyone, and I was able to live a happy life.

If you have that feeling, please let me know how you feel at this place if you don't mind.
Or, for example, please let me hear your story at a sharing meeting where I also participate.

You're never alone. Nor is it your sole responsibility.

Your daughter will continue to live with you and everyone from now on.

Please continue to live your own life peacefully while cherishing your relationship with your daughter.

You have always been dear to your daughter at all times.

I don't think there's anything more painful than the suicide of my beloved child. First of all, I pray for your souls.
It may be true that no one other than the person himself knows why he committed suicide. Actually, my nephew also passed away at the age of 25. Also, several daughters of the parishioners have also lost their lives. There were times when they passed away at the end of the month even though they showed up at the prayer party at the beginning of the month.
I felt powerless myself, and I was worried about how to talk to my family.
The way we perceive death, and the way we think about living, seem to have changed since that experience.
In this life, we have had a close relationship and have lived as parents and children. It's still going on. I think what each of them experienced in the form of suicide of an important family member also has a deep meaning.
There are probably people who say a lot of things irresponsibly. There are probably people who don't know how to speak up.

There are probably many things that only experienced people understand. It's the same for Manaka.
Someday we will all leave this world. If so, you'll have a variety of experiences while you're being kept alive, so let's make the switch yourself.

The issue of attaining Buddhism is different, so it would be nice if Manaka-san lived according to Manama-san. Of course, my daughter is there at the same time.
At that time, I should have done this... regret doesn't come first. Please live together from now on. Finally, “why?” You may be able to understand it when this world ends. But that's fine.

Good evening. My name is Kameyama Junshi.

Please forgive me for responding at such a late time due to the fact that I myself usually have a different job.

Well, I'm still thinking about suicide, but I read this consultation, and I wanted to answer it even though it's incomplete.

First of all, it is quite natural that everyone would want to know if they don't understand why they committed suicide. This is probably because I think that by knowing the reason, I can get even a little closer to the feelings of the deceased and understand them. We want to stand in the state of mind that the deceased was worried about and chose the option of suicide. However, on the other hand, if you know the reason for suicide, I think you will inevitably feel remorseful about why they didn't notice such a thing. This is a conflict in our hearts that can occur over the death of a loved one, even if it is not suicide. In other words, whether we know or not why we committed suicide, we probably cannot fill the grief in our hearts caused by the fact that our loved one died by suicide.
Therefore, I think what bereaved families can do is respect people who have committed suicide. I don't think we should ever blame someone who committed suicide. There, I don't question the pros and cons of suicide, but I think it is dignity for the deceased who couldn't help but choose suicide, acknowledging the deceased who couldn't help but choose such a choice, no matter what reason, that is a form of being close to the deceased.

These are my answers. And I hope this answer from me can help you even a little bit.
