<human>: Condense the text into a few key points

I'm not exactly an avid poster, and hardly a lurker on reddit, but I seriously need some advice here. Currently my 2 younger brothers both nearly 16, have been seriously getting on my last nerves, and my parents especially. They disregard any form of authority, and they are just getting worse and worse and of recently I learned that apparently they've been getting into shit like drug dealing.

So at this moment, my family is in near shambles, parents looking at a divorce, recently lost a lot of money trying to keep afloat the family business, dealing with a decent amount of debt, and currently dealing with a suing employee. My father is completely useless at shit like this and my mom is doing what she can to keep this slowly breaking family together for at least another 2 years so they will be 18 and leaving.

Now I'm asking reddit for help because honestly, I can't take it anymore, and my mom is quite literally (and I don't mean figuratively literal) dying from the stress. She's been to doctors about her problem, and is getting the same answers to what's causing them. I'm not saying that I'm not the cause of any of her stress, but I am saying that I'm pretty much the only one in our entire family that is trying to help her, even if only a little.
<bot>: Family is breaking, mom is working herself to death, douchebag brothers are getting worse and worse. I just want to know what I can do to help, because I'm lost...
