depressed much? :(

So I've been pretty confused and sad lately. There's been a lot going on with my family and I'm stressed out by school. Let's start with my family. First of all my aunt and uncle are separating. Again. By that I mean my uncle is leaving my aunt and cousins. My aunt doesn't have a car or job to continue to pay rent in the apartment that they are currently living in, so they are moving in with Shaina, my 19 year old cousin who owns her house. The bad part of this is that now Dennis is being kicked out. She has given him until the 1st of February to find a new place, except he is broke. He was dating this girl Jessica, who he claims to be "in love with" and cold see himself marrying her, but nobody in my family likes her. She used him plain and simple. When she was younger she moved out of her mom's house because she didn't want to live by her rules so she moved in with her boyfriend who paid for everything for her. Finally he dumped her and he wanted all of his money back 9apparently she owed him a lot and STILL hasn't paid him for anything). Last summer Dennis and her hooked up (did I mention she slept with and dated his best friend first?) Well they got together and she practically moved in with Dennis and Shaina. She doesn't pay for anything, Dennis buys her everything from clothes to shoes to designer purses. Not to mention dinner every night. He took her to a Giant's game and got front row seats even. Dennis has always treated his girls really well, so it's not like this was out of character for him. Except Jessica has done some deceitful things, like claiming her car was broken into and her ipod, camera and credit card were stolen. But there were a few flaws in this scenario. She has two ipods, the ipod nano and an ipod touch but the nano was stolen, her camera was stolen but they left the memory card, and her wallet was there but only the one credit card was missing. I mean if I were going to break into someones car and steal stuff I would take the whole wallet, the ipod touch, and the whole camera. Hell I'd probably take her entire purse. Also she says it was broken into on her school campus, which means there would be security cameras but she never pursued that to get her things back. I honestly think she sold both of them for extra money. Next, she claims she was fired from her job, but my brother knows her manager and he said she quit. Why would she lie about that? Can you tell I don't like her? Well anyways, my entire family knew she was using him but he was blind to it, he refused to acknowledge it. Finally she dumped him because he is broke and cant treat her to expensive dinners anymore. But now he is severely depressed, I've never seen him like this before, it's devastating. Not to mention Shaina is screwing him over  by not giving him  back his $300 deposit because she was recently fired (for real, not like Jessica) and she wants him to pay to have the carpets cleaned before he moves out, but she knows he can't afford that right now. All of this is really weighing down on me and I don't know what to do to help. My parents and my brother continue to argue because he is irresponsible with his money, and because he wants to get back together with Jessica and my mom told him that if he does that he would kill her. So basically my mom is forcing him to choose between Jessica or herself. I'm afraid to find out who he is going to choose :( Well I think this is enough to tell you guys for now, because this isn't even half of my problems.
