Saying goodbye is increadibly hard, and I'm not sure that there is a specific way to say goodbye! its a personal thing that only you can really do in your own way. I'd agree to go somewhere where you hung out a lot and remember the good times, it helps to ease the pain a bit......and maybe pray that God would be with you, and comfort you.........or have a religious friend pray for you. Other than that all I can do is pray, cause I dont know how you personally need to handle this. I'm sorry for your loss
I'm sorry to hear that, but he is gone, the chemical reactions no longer happen in his brain, his heart is no longer pumping blood, he's gone, and you have to move on, its terrible to hear that, but if you need to believe, there's nothing wrong with that.
