Tell me sickness will end!

Jenn
Hi ladies, 
I am 13 weeks and I just need a reminder that this horrific all day nausea and vomiting and inability to eat will end! 
With my daughter, I was sick until about 15-16 weeks and I'm trying to remember that but I'm just getting so depressed. I can't play with my daughter (she's 2) and am just in bed almost 24/7 so sick.  
Ahhhhhh why can't I have those great pregnancies people love???
