How do you enjoy being pregnant?

Temi

My doctor told me that I should be enjoying this time... but how? Most days, my back hurts and I am combating a headache. I always feel dehydrated no matter how much water I drink. It seems like my husband is becoming less and less "there" or maybe I am being too sensitive and I feel like I am losing my balance on things (I am a 20 y/o store manager, Full time student although it is online, and right now, my marriage is not fulfilling). What do I do? Shit. Where do I start?
