https://grief.com/ – Ok, I know the site is the antithesis of what you want to see when you’re grieving in your 30s. It kind of reminds me of my grandmother’s living room. Bare with it though, it has great resources that I promise don’t suck.
https://www.myjewishlearning.com/category/mourn/ – I’m not Jewish, but my therapist is. We often speak of different cultures and how they handle and perceive death. Once, he told me that some Jewish denominations believe that there is a spiritual gift of premonition of death (mentioned after I told him that I knew my mother had died when I woke up). From there, I started looking in to how the Jewish religion treats death, loss, mourning, and the afterlife. While it’s not my exact belief system, there’s a strange comfort that there is a sense of tradition even in death. I think it’s kind of a shame that western cultures never adopted Shiva and Sheloshim, because it’s clear we ignore death until it causes us trauma.
