Hubby doesnt get it

I am 6 weeks 3 days pregnant with my first and morning sickness has hit full on as well as awful fatigue. Yesterday i think i slept more than i was awake and then we went to dinner with my parents. Got back to my parents house and promotly threw up everything. This morning i threw up 5 times in an hour trying to get ready for work so i called in. And my husband keeps saying things to me like "you just have to fight through it" and "gotta find a way to get over this so you dont fall further behind at work". I have explained time and time again this isnt like having a cold and going to work anyway. This is fully out of my control and i cant help it. I am a home based therapist. I am in and out of a car and my clients homes all day long. Not exactly easy to do when i am so nauseous. Anyone else have a hubby who just doesnt get it?
