2ND pregnancy super tired!

Regency
Hello is the any one out there who already has kids or even just one, and has another baby on the way? How are y'all juggling being a mom, working or even staying at home and your husband? I am 22 weeks today and soooooo tired! I'm super thankful and blessed to be pregnant with our second, but I've been in tears b.c I'm super tired, back hurts, head aches, plus I stand on my feet all day, and more! I want to be the best mom I can to our 5yr old daughter, and a good wife. (he's not complaining at all he's great) but I don't feel like having sex at all, and want to do nothing but sleep. Any advice ladies or encouraging words.
