Aww... you gotta leave? We'll miss you, but thanks for the heads-up. Now, on to more serious matters.
The first is important, a clean, organized enviroment can make you feel better and more relaxed.
The second is also important as it takes time. And patience. And practice. And good time management. The last is my biggest weakness. Darned procrastination.
The last is beyond important. Family matters. No ifs, ands, or buts about it. Just remember that both your parents are humans and humans are, as a rule, ignorant. This is something that needs to be settled between your parents in a one-on-one grown-up-like discussion(not an argument and most likely not with you). The first step in solving a problem is to realize there is one. The second step is to identify the problem. The third step is to analyze what is causing the problem. The fourth is to work towards solving the problem. As I don't know the details, I can't help you much futher, but I do hope for the best.
And remember, the best may not always be what you want.
