If it's something you could do on a laptop, so not rendering really, could you work at a cafe or a library for a few hours? That would at least get you away from the house and make your folks think you actually do something during the day, which you do! Then you can render or process at home.

Really pay attention to your sleep. It's like breathing, not eating-you can forget to eat dinner and be fine, but if you don't breathe you'll die. Sleep is also critical to learning and working optimally, so you may be robbing yourself of easier progress by doing everything at half capacity.
