So incredibly sad...

I'm 9.5 weeks and the past few days I've felt nothing but overwhelming sadness. I don't want to do anything. No work, no school, I don't even want to get out of bed or even eat. Obviously I'm eating but I just don't want to. My s/o has noticed that I do t want to do anything and I can tell he's getting frustrated but I don't know what to do. Is it normal to feel this sad??
