It IS really hard, and I know how you feel. When our friends lost their baby, it just seems like no words are adequate. I'm sorry sounds so hollow, and nothing you say really sounds right. As others have said, try to be there and be support. People are all around when it first happens, but then they either disappear due to dicomfort, like others have said, or they just go on with their lives and the person with the loss is still feeling it so strongly. They can begin to feel alone after the first rush of people stops coming around. I'm sorry for their loss, it is especially harder when they are young like that. Thoughts and prayers for them, and all involved.
