This is Kawaguchi Hidetoshi. This is my humble answer to the question.
First, just because you die doesn't mean your suffering will go away. If you die and the suffering goes away, everyone can do it quickly, whatever method you use, so it would be good if you die right away. However, this is an extreme rhetoric, and it is rejected in Buddhism as an evil opinion.
We have received the following questions before, and we have answered them.
The question was “If I die, wouldn't it be nothing? ”

Regarding matters after death, I have dealt with the two points of whether answers should be rejected as “unrecorded,” or whether it is necessary to describe the state of mind (mental inheritance/mental continuum) that continues after death.
In the recent comments below, the latter has been treated more aggressively, so please refer to it.
“About after death”

Anyway, there is of course “death suffering” as one of our eight sufferings (suffering, old suffering, sickness, death suffering, separation from love, grudge and suffering, unrequited suffering, and five great suffering).
Shakyamuni taught the teaching of what should be done to eliminate the suffering of eight struggles represented by these. This is the truth called the “Four Sacred Deceptions” (suffering, gathering, destruction, path).
Therefore, by studying and practicing Buddhism, it is our goal to make an effort to firmly eradicate such suffering.
We have dealt with the Four Noble Truths in the following questions until now, so I hope you can refer to them.

I hope you will take this opportunity to become even more interested in Buddhism and continue your studies. By all means, let's work hard together.
