Why is pregnancy so difficult?!?

Gabriela • First time mom. 23. Due 06.26.17
I am only 13 weeks pregnant, and I'm tired of all this. Tired of having to pee all the time, tired of having to drink water all the time, tired of going to the bathroom all the time, tired of having to take vitamins, tired of having to eat because If I don't eat, I'll get sick. It's just so much. Oh and the constant nausea. 
And I know it's just going to get harder. Jeeze. 
What can I do to relax and get through this period better? I am happy to have my baby, but I am a first time mom and this can be overwhelming.
Thanks!
