When I'm at work...

When I'm at work I feel beyond drained & tired , but whenever I'm at home .. I feel completely fine 😑 If I was to rest & sit down I'll feel better but as soon as I get back up to start working , my body starts telling me to go sit back down 😩 I don't want my manager to think that I can't work because of the pregnancy because I can but I just need a lot more breaks than everybody else lol .
