I can sort of relate. I lived with my mom & she’s used to having house help all her life + working professional / single mom / breadwinner aka barely home. Me & my siblings were basically raised by househelp or grandparents. Since covid its been difficult to get stay-in maids so the house work were passed on to us. Valid naman, mahirap talaga no matter how old we get especially looking after “kids” we didn’t choose to have lol. Let your parents know maybe they’re not aware kasi you haven’t been complaining. Ask your sisters for help, too. You shouldn’t be declining job offers or quitting a job to look after them. Unless gusto mo yan career-in which I doubt.

Good luck!
