Don't be fooled by your dad's "Goods sides," there is no silver lining to abuse. His best days compared to his worst days are always going to be one step forward and two steps back. The best thing you can do is protect whatever level of autonomy you can control, be it personal funds or what, until you're old enough to own your own bank account, get a job and work on getting the hell out. I grew up in an extremely abusive household and was homeschooled too. I understand that the lack of energy to get anything done, and the lacking will to continue on because of the abuse. It is going to be tough, but I guarantee if you put in the work and get outta there, whatever life you can make will feel so much greater.
I ended up having to go homeless to get out, and even I still managed to make some semblance of my own life. Know that however bad it may seem, being able to live your own life not in fear of anyone else is not an unreachable goal. Good luck, my dude.
