I an sorry for your loss, reading this brought back fresh memories of when I lost my dad. He died of a maasive stroke while walking in the park. I was notified by a police officer. I felt like I should have known but I didnt and I cant really describe accurately how his death affected me but I will tell you that I wouldnt wish it on my worst enemy. Its been 11 years ago and I still miss him everyday. Its funny as much as we like to think otherwise, we never outgrow our dad. May you find peace.
