Anyone else have this issue?

So I am 12 weeks 2 days now and my boyfriend has no idea how hard this pregnancy has been. I got diagnosed with hyperemesis gravidarum last week. Up until then I've literally been laying in bed or on the couch because of how crappy I feel. He is getting very frustrated because I haven't cleaned the house, done laundry, or cooked in weeks. How do I get him to understand that it's really hard to do anything when I'm so sick?
