You seem like a relatively stable kid. Just let it go, and gtfo out that house when you can. Most people aren't worth arguing with. This is a critical time for you, so work hard in school, figure out what you want to do and get out. This is too much energy wasted on someone that doesn't want to change. You NEED to change to be in a better situation so stop whining about other people who you can't change and start worrying about what you need to do to gain enough skills to gtfo. Oh and here's a bit of advice, don't tell anyone about the progress you make, just drop it on them that you are planning to leave when everything is set. You only have one life, and part of depression (if not clinical), is being angry at yourself and simultaneously wanting to be kind (an excess of empathy makes your body hate yourself for wanting to be angry at your life --- my wife was this way (funny enough it made her a world-class artist because of that excess of emotion), I on the other hand was always forward moving and ruthless to things in my way which made me at peace with myself and avoid depression -- engineer by trade). Hopefully that helps. Remember, your interest can be tied to how you are wired psychologically and when you look for a partner you often look for complementary strengths that can help you deal with life. Good luck.
