There is a deep fallacy in judging some one else's level of consciousness, and there is a big gap between becoming aware of a level of consciousness and transcending it. Consciousness unfolds before you like a staircase. Just because you can see a step doesn't mean you're on it; and just because you can see somebody else on the staircase doesn't mean they're on a step below. But you can't walk up while you're looking at other people's feet. You also cannot skip steps, and you cannot say that the last step is any better or more important than the first. In other words and in all sincerity, until you have lost all desire to judge, you are unqualified to do so. There's a reason this subject (judging) has been addressed by every spiritual discipline.
And besides, even if global consciousness were to shift tomorrow, there would still be a spectrum of levels. Meaning that we will always be working with people who are both higher and lower in conscious development than ourselves. In fact, by trying to raise your own consciousness, you are effectively attempting to increase the number of people lower than yourself. So either get used to it, or start giving them a hand up; preferably both.
That said, difficult family is not easy to deal with. As pretty much every person with a family can attest. But it doesn't do your own awareness any good to escape it, deny it, or begrudge it. In fact, all of those things cause awareness to contract. They are your family, and whatever cosmology you choose to explain it, that's the way the cards were dealt and if you are to continue your own expansion, you need to fully address this.
So I would say the real question for you to examine is why this is a problem for you? Why do you allow their behavior to affect your sense of autonomy or well-being? Why do you have a problem with what you perceive as their level of consciousness? So you don't want to be a therapist, but you're doing it. Something's got to give. Figure out why you behave the way you do and why you react to their behavior the way you do, and your problem will be closer to solved. Then address it with them (not at them) and you may find everyone can grow a bit in the solving.
