absolutely no energy

I'm 37w and I can't come up with the energy to do anything !! My boyfriend took me to breakfast before he heads off to work and I come home throw some laundry in the washer and come upstairs and i feel like I've ran a marathon! I feel so lazy but I legit don't have the energy to do anything 😩 anyone else ? I get so bored and then when I get up to do something I totally regret it lol
