Feeling sad and guilty

Ever since being 6 weeks pregnant, I've been dealing with morning sickness. I have my good days and my bad days. whenever I'm feeling sick all I want to do is rest. I feel like my fiancé just doesn't understand what I am feeling, like im using it as an excuse to be lazy. I feel like he's giving me the cold shoulder. When I ask him what's wrong he says he's tired. I don't know if it's just me being hormonal and over reacting, I just want to feel "normal" again. I'm so sick of feeling hungry, tired and sick all the time! :'(
