39 weeks and need to vent

I’m at FTM and I’m 39 weeks and 4 days. My sister got a mommy makeover surgery and is staying our house for recovery. I live with my grandma & I had told my sister she was getting her surgery very close to my due date but she insisted she would be better. She can’t get up on her own and can’t use the bathroom on her own. My house has been a MAD HOUSE the past week trying to help her. My niece and nephew and mom have been staying here too but everyone has to go back to work and can’t be up with night with her so I have been. I don’t know the last time I’ve gotten a good night sleep since I’m up with her every hour re-adjusting her and helping her get to the bathroom. I don’t mean to sound selfish or rude I’m just absolutely exhausted and tired of sleeping on the couch waking up to help her especially so close to my due date 😔😔
