How do you deal?

Ladies who have had kids before.. how do you deal with the 3rd trimester being so crappy? I can’t find a comfy spot to sit, stand, or lay down.. I’m nauseous.. I’ve got this constant cold that isn’t a cold.. And I’m so tired.. I could stay in bed and sleep all day, but I’m fighting naps because I always wake up disoriented and even more tired than before.. I’ve still got 10 weeks of this, and I’m not stopping work till the end of September.. seriously, how do you do this?
