Do I have a right to be so angry with my mom and dad? (It might seem long, but it's really not)?

My dad keeps doing stupid, mindless things that bring me and my family more and more in debt, which makes me angry. My mom also gets angry, but she is a lot worse. She's so incredibly pessimistic and always complains about how our lives are over. She also indirectly insults me, saying I would be lucky if I got into a clown college (I'm about to be a senior in high school), and says I might become a looser like my dad. I have pretty good grades tho (3.5/3.6), and I go to a really hard/prestigious private school, and I'm retaking my SAT in the fall. I also am a really good opera singer, so I know there's hope, but it really pisses me off when she says stuff like that to me! I help her out around the house, but she says it's not enough. Both of them are in their own worlds. My dad escapes reality by being overly optimistic and not taking charge. My mom never stops complaining and throws a pity party EVERY SINGLE NIGHT!!!!! I wish we could just be a family again, and debt can't get in the way of that, yet they are letting it tear us apart. I got mad at both of them last night, and now I'm staying with my sister in her apartment across town for the weekend (or longer). Am I being a bad daughter? Or do I have a right to be angry with them?
