How do I make it go away!! (Morning sickness)

I'm 6 weeks and 3 days I spent last week worried about miscarrying agaim and this week I'm tired 24/7 but cant sleep longer than a few hours and morning sickness wont stop!!! Its all day sickness the smell of everything is disgusting and what smells good I can't eat more than a few bites without it making me nauseous. Ice and water is my bestfriend but will keep me in the bathroom even more. And the constipation is horrible! What can I do to be able to eat the things I like and fix my always upset tummy ?
