I don't really know what to say. I don't deal with death well, I mean obviously it's not something anyone really, gets used to but.... in my head, it's people leaving. Because of my adoption, It's my biggest fear, being left...
I'm very sorry for your loss. Is there anyone in your family you can talk too about grieving, etc? I think it's important to let people know how you feel. You said you were the last to know, maybe they were trying to spare you some distress but if you feel you'd rather be more involved, you may want to let them know.
I'm sorry if this sounds patronising, it's not the intention...
