Lost my baby at 32 weeks-don't know how to cope with everything.

Its been 6 days now that I've lost my baby girl without no reason given and I still cannot believe it. I still can't look in my husbands eyes and I dont know how to tell our son about all that. I feel beyong guilty and heartbroken I feel like I'm the reason why and I'm scared and I miss her already I don't know what to do. They suggested a funeral but I can't do that I just know that.
