I understand what you are feeling feeling like someone took away your opportunity to be with them even at the final second. My brother died May 28, 2006 from a motorcycle accident hanging out at a memorial day barbeque with his friends. The police came to my moms house at 8pm and told her, at that time he was already taken to the medical examiners office and none of us was allowed to see him considering the circumstances. I live across the street from my mom and came over as soon as my dad called me. It all felt so confusing. He was just at the house that morning and now they say he was dead. I was so confused and hurt. My brother's girlfriend who had been at the party with him showed up around 9 or 10 and she said that after he had been missing from the party for a couple hours and she wanted to go home, her friend took her out to look for him and they found him dead with the police blocking the area off. Later I found out that it wasn't true. I foudn out that the house was around the block from where he died and he was out there with soem people from the party, which meant she new when it happened. I felt like she deprived us, his family of the opportunity to be their for him. To come and get him, to hold him for one more second. I try to tell myself that they are tryig to save you the pain of the issue, of your sister being so sick and possibly dying. Your mom wanted to protect you from that because that's what mom's do. They protect their kids from the nasty truth of the world to keep any pain they can from their heart. Maybe to his girlfriend she was sparing us this, but for me she took it away. When I go to where he died inside I feel like he is still their waiting for one of us to come because we never showed up. He died and nobody even came for him.
