My 20 yo sister left high school 2 years ago, with an incomplete diploma. She preferred to procrastinate and be on tiktok rather than studying and attending class. Both extended and close family members pleaded with her to take her studies seriously, but it just got worse.

Nowadays, she just lays in bed, scrolls on tiktok all day, with zero personal hygiene. She still lives at home, and her room is in a horrible state, we even found maggots in the room because she leaves food/dirty dishes on the floor.

Everyone encouraged her to get a summer job, while in her teens and she refused, she still refuses to look for a job.

My mom seems to have given up, and shes also getting older. She has mentioned before that she expects me to take care of my sister when she's gone, and this worries me? I need some guidance, please?
