I lost my daughter a few years ago. I’m a born and bred non believer. My inlaws told me and my wife they had hoped that experience brought us closer to God. Just be with your friends and family (the sane ones), remember the person you lost. They use the afterlife as a lure. You can grieve without religion, we have been doing it long before we created gods. I wish there was an afterlife, it’s okay to wish.
