Is it just the period ?

I don't know if it's just the period making me feel weird or why am I'm suddenly sad to be away from my babe. I miss sleeping on his chest, having him hug me from behind, sucking on my boobs when we were in the car (it was at night), having him kiss my neck, kiss my forehead.
I mean we met just yesterday for New Year's but now i already miss him terribly...
