Omg, I cannot take these family problems screwing up my life xl..!?

You need to find other places to hang out as much as possible, so you're not so overwhelmed with this kind of chaos. Are you old enough to work? Check out the library or community spaces like parks, pools, or museums. There are a TON of programs for young people at all times of the year. Get involved with positive people who can offset the negativity at home. Last, rather than focus on these people, focus on yourself and how to feel productive and peaceful. You generally GET what you concentrate on.
