Know my grief is not the same as your daughter's but I myself have blamed God then felt horrible for it later. Its really hard to deal with. Just being there for her is a great thing I'm sure. Her getting angry and jealous goes along with it. If she has depression and not saying she does but that can make it worse. Depression is a mean beast. I have it and have it before I lost my mom and its got worse since then . Just listen to her, be there for her . Its all you can do.
