Don't Know What To Do Anymore

I delivered my son three weeks ago, he passed away. I was 20Weeks pregnant. I don't know what to do anymore. My entire world is shattered. I haven't even been able to lay him to rest yet. I can barely function. All I ever think about is my baby boy. My heart hurts. My eyes hurt from crying. I don't think I'm ever going to be okay again. I miss him so much. It's not fair, he shouldn't have been taken away from me. Everyone asks me how I'm doing, if I'm okay.. I lie and say yes. I don't want to be a burden on anyone. I don't want anyone to know that getting out of bed each day is a struggle, that going to sleep is basically impossible and when I do sleep I wake up crying and screaming, I don't want anyone to know how hard it is not to self harm, it's been so long since I have, I don't want anyone to know how hard it's become to even breathe anymore. My husband just continued his life as if nothing happened. I don't know what to do anymore. I'm so tired of everyone telling me I'm only 23 and I can try again, it's not the end of the world. Little do they know it is the end of the world, the end of my world.. I guess they'll understand soon enough..
