When a body from you body, your own blood and soul dies, a part of you dies. The most fucked up thing to say to the person who lost a child is to dance, cheer up, have another child, live and get better, move about or whatever else crazy shit people came up with. There is no light without darkness. You need to die with the loved one to come back to life. No amount of bullshit to cheer you up can make you feel better.
