Feel like crap

I am almost 10 weeks. I am tired of all the headaches every day and the nausea. I feel completely fine until about 10 minutes after I get out of bed. Then I start feeling crappy. I feel horrible because it makes it so hard to take care of our other 3 kiddos. I know the headaches won't go away until after baby is born but i at least hope the nausea goes away soon.
