Sending hugs and support. That is more than anyone should have to bear in a short amount of time. Of course you are having a hard time. Can you talk a walk or step outside and take in some fresh air? Or write your feelings out just for release?
Feel your feelings - we are here to listen. 
I am so sorry. Come here to the virtual couch and tell us about these people you loved and have lost, when you can. (Someone asked me about my dad the other day and it was comforting to talk about him)
It’s okay to feel overwhelmed. Just get through one hour at a time.
It’s totally understandable to have such a hard day after so much loss and bad news. You can come here anytime, night or day, and vent to us. We have big shoulders.
Just sending more virtual hugs and support. So sorry you’re having such a tough time.
That is an almost impossibly heavy load of grief to carry. I hope you are able to find some small way to rest or be distracted from it all.
Oh man! That is a lot of loss. I am so sorry…. Hang in there !
