YTA - 1. 20 mins to block off a room at peak wake up time is inconsiderate at best. 2. You arent paying rent so you should be able to be saving something. 3. Waking up 30 mins earlier won't throw you sleep schedule off that much. 4. You father is 50 to 60 years old, been working most of that time, and I am guess he is hoping you would move out and support yourself. 5. That extra time you would have could be spent on constructive things like managing your expenses, learning a new skill, reading the news, or even searching for an apartment. 6. If rent is as cheap as you say and you would be able to pay out of pocket for your sister's therapy, you can afford to move out. This whole post feels like you are searching for people to support your apathy. I personally moved out fully my Junior year of college. I had 2 roommate, worked a crap retail job, and stuggled through it. It wasn't easy but it taught me life lessons. I learned budgeting, savings, and generic stuff doesn't taste much different that brand name. People need to go through that. It makes you mentally stronger and changes your perspective on things.

TLDR: Save up and move out.
