Today marks four months since my daughter Rehtaeh ended her life. It's said that losing a child is the hardest thing a person can experience and if there is something worse I can't imagine what it could possibly be. The last four months have been hell peppered with smiles as I think back on memories. I cherish those when they come, even if they last for only a moment. This is the hardest thing I have ever faced. This is an ocean of grief. I'm treading water in a tidal wave of pain, disbelief, anger, sadness, waves and waves of heartache.
