Ask yourself this question; Did "you" do anything to cause ANY of this? The answer is of course, "nope." Do not try to give advise to your parents. Do not try to join in on the yelling. Do not even think about who is being fair and who isn't. You can't possibly know. What you hear and/or what you're parents say, may only be "their truth", not reality. First thing "in your power of control" is to know for a fact, there is very little at all "you" can do. What you might do is; quietly and without drawing attention to yourself, offer to play or show something to your siblings. Try to get them away from the direct area of the problem. Chances are, with all the yelling, your parents won't notice. Don't let your siblings know what you're really doing. Next, just go to your school office and ask to see the councilor there. You're friends won't know. The councilors are not allowed to break the "law" of confidence (they can't tell anyone)... unless someone is being hurt. The counselor can tell you what to tell your friends if you get called down to the office ...to meet with them. They're very creative. IT WILL HELP. If you don't help yourself, how can you be of any help to someone else? Or for example, if you are sick in bed and too sick to help someone else, then how can you help them? Take care of yourself, love yourself. This way, you'll be able to be an all around hero. Especially to your siblings.
