Anxiety of going back to work

I'm supposed to go back to work tomorrow and every time I think about it, I have a panic attack. I've been out for 3 days since my D&C. I know everyone is wondering where am I. A few knew I was pregnant and only 2 knew of the miscarriage. I have to see so many faces and find a way to get caught up where I left off. I don't want people continuously asking if I'm okay, while the others try to figure things out. I'm so scared and nervous at the same time. Too much emotions going on. Still cramping bad off and on (I can't tolerate pain). I just want to stay on my couch in the dark as I have been. Thank you for letting me vent.
