How Would You Feel If Your Child Commited Suicide ?

To all the parents out there, or anyone really, how would you feel if you one day came home, and you saw your child laying dead on the ground covered in their own vomit, or if you're at work and you suddenly get a call asking you to come identify the body of a child who jumped off a building or even you walk into their room with a gun in their hands and a gunshot between their eyes ?

I'm just curious to see how one would respond.
