Losing people we cherish is a very painful experience. I understand the anguish you felt when you attended to your two friends in their sick conditions. But I think the best is to allow them to just go and rest than continue to experience that much pain. The only thing you can take away from this your experience is to cherish friends and family of yours that are still alive and spend time with them.
Thanks for writing.
It is a good recommendation, to take advantage of the time with our loved ones, to enjoy their company. Although it may seem contradictory, that is life, we do not want them to leave, but we do not want them to suffer either, we were not born to die. Thank you for your comment.
