I think the process should be as rational as possible. It is very difficult to do, but it is always as close as possible. I understand that the ideal conditions are when you have exhausted the possibilities in your mind. Then you need to be at peace with the life you are leaving behind. There should be no blame or feelings of guilt. You should be fully aware that life is just an accident and that the suffering you are going through has no purpose. Therefore, if you still have traces of religion, beliefs in life after death, etc., you should not attempt it. I do not believe that anyone is prepared in these cases and in other situations. Of course, no one can determine what is best but you yourself, this is just my point of view.
