Since I was 8 years old, (I am 15 now) my mom was extremely sick. She had a rare disease called scleroderma, she could barely walk, and most definitely could not cook or clean or do laundry or really anything besides lie down. For 6 years I took over cooking for the family, cleaning up after my siblings and parents, and taking care of my mom. I washed her and changed her clothes, brushed her hair and fed her. All while balancing a regular school life. I schooled myself at home because I could not go to public school. She left this world at the end of 2019. I wouldn't consider this a considerate thing to do, as there anyone in my position would have done the same, but that's the only thing I can think of at the moment :)
