Nauseous or starving

I'm 10 weeks pregnant and the whole morning sickness kicked me hard this week. It's gotten to the point where I just hear about food or thinking about food will get me gagging. I'm so scared of eating that I dont eat anything at all till I can feel my stomach eating itself. I know it's not healthy. My mother told me to eat. Throw up. And then eat again... I cant do it. So far I've dropped 7lbs in 5 weeks. . Gatorade doesnt help. Small snacks dont help. Saltines dont do anything anymore. All I wanna do is curl up and sleep this morning sickness away... wake me up at 13 weeks and this whole feeling sick passes.
