Do any 2x+ mamas have any advice on battling fatigue and food aversions?

I am miserable. I literally can only eat one meal a day. I'm not throwing up I just feel like I'm on the verge all day long. I cant even THINK about food.

And the fatigue. Omg. I have a 19 month old who is super busy but I just cant even muster energy to play. And I feel horrible. I just want to sleep all day. And of course I can't deal with the smell or taste of coffee currently so also...no caffeine intake.

Any advice? Sympathy? Empathy? Lol
