Aniexty?

Megan • 24, have a 6 year old girl and an amazing boyfriend! Expecting #2 November of 2015!!
My daughter is six, I'm 16weeks with #2 they have different dads, so my 6 year old just went with her dad for a few days for the first time in a month..I feel like I'm having separation anxiety...or hormones idk but I used to like a break now I can hardly sleep Bc she's not here!!
