I'm having a hard time getting passed the loss of my son

I've been feeling so depressed ever since my son was stillborn one week ago at 21 week July 13, 2015 I feel like I can't go on I tried to hurt myself I know it's not gonna be a easy road but it's days when I'm alone and feel like I can't go on I don't know what to do I pretend like I'm ok when people are around or ask me how I'm doing I feel weak empty and sad please somebody help me to get through
