Tell Me What Do You Do When It All Falls Apart?

I'm so fucking confused and worried about life right now. I was so happy and carefree but now I'm worried to the extreme. Things are falling through the cracks more and more all the time. First there was the situation with my brother; and that is definately NOT resolved. It's not helping anything. I feel like my family is falling apart and it seems like no one notices or even cares for that matter. I have this massive weight on my shoulders and I don't know how long I'm gonna be able to deal with it. I'm trying so hard. I need my family, I need everything to be ok. I'm so terrified of what could happen and I feel like I have no one to talk to. We're having money troubles and that's not helping my parents relationship with each other or us. I wish there was something I could do. I've thought about just quitting school for now and getting a full-time job or multiple part-time jobs to help out in some way. I could go back to school once things start looking up around here. I can't stand to see them struggle like this. I'm so overly frustrated. I'm trying to help out as much as I can here. I cook, clean, go where ever I have to. I just really need things to work out. I don't know what to do. I'm tired of seeing my mom and dad fight, my mom cry and my dad angry. I just need a little winter miracle.
