This is Kawaguchi Hidetoshi. This is my humble answer to the question.
It looks like you're really having a hard time...
If you don't mind, I would be grateful if you could consult with hasunoha about the details as much as possible.
Until now, we have answered the following questions about suicide and matters after death.
“About Suicide and Suicide”

“About after death”

“Doesn't suicide end anything?” ... Buddhism denies both the theory of permanent residence and the theory of annihilation, and also denies the theory of substance. Therefore, I don't think it's going to die, then everything will end, and it will be nothing. Of course, color and body as one of the five effects (color, reception, thought, action, consciousness) lose their function and action, so it cannot be said that they are the same as the state we are currently living in. Also, other effects affected by the body also disappear or weaken, but even if the body is lost, it is natural that other effects are kept fine in mental inheritance, and furthermore, there are cases where that mental inheritance maintains the potential (possibility) of having a physical body, and eventually it is possible to prepare for the five functions again. However, as in the analogy of the “blind turtle driftwood,” it is truly difficult to be personally affected, and for example, if we were to be able to obtain a human body on this earth again and live the way we do now... honestly, the probability is close to a miracle. I really want you to take good care of your current life.
“Will the Buddha send me to hell as punishment?” ... It's not that the Buddha makes you go to a bad place as punishment; it's just your own actions (karma) that determine your own destination. If good deeds can be accumulated along with the relationship with the Buddha, good deeds can also be hoped, but since a relationship with the Buddha may be one of the causes or conditions for a good destination, it is by no means the only absolute cause or condition. What is most important depends only on how you act.
Due to the character limit, up to this point. Anyway, depending on what you do better in the future, you will definitely be able to hope for better results. I would like you to stop thinking about suicide.
