Hard to enjoy my pregnancy when I feel like crap

Trying to keep this pregnancy a secret until I'm in the clear is becoming harder and harder. I'm sure people are starting to wonder why I don't socialize. In person or on the phone. I feel terrible and I can't say anything. All I want to do is walk around happy and be thankful that I am pregnant. My poor husband is worried about me... I keep telling him I'm okay. But when it gets bad, I can't help but express how crappy I feel. I'm two months today. Hoping these feelings subside soon. I'm losing my mind!!
