Life In Losses

What do you do when it feels like nothing is alright? Apparently tonight what I do is break down and cry. I haven't really done that lately. I'm more likely to hit something and get over it, or run it out. But tonight none of that was going to work. My iPod and crying seemed to be the way.
I was arguing with my dad, and I walked out, because I can't stand it. I hate it. It doesn't matter what we argue about. Whatever I say I just get shot down. He doesn't really take in what I say, he just has to find a way to come back at me and make me "wrong." Tonight this started over me telling my brother to not call my undercooked brownie the "burn victim." I don't really appreciate my cooking being insulted, especially when it's in such a stupid way. But this led to me being told to be more tolerant of my brother, because he's not having it easy right now. WTF. My brother is a horrible, lazy person. He does nothing. He just stays at home all day, everyday. He doesn't help round the house. I spend most days at school, another day at work, and have one free day a week. I still manage to help round the house, not that anyone notices. But he's the one having a hard time. All I have lately is stress. But they're worried he's depressed and are telling me to go easy on him. I want to give up. I don't want all the stress anymore. I want to do the things I want to do, instead of worrying about school and other things all the time. It doesn't seem my parents realise how on edge I am, though. Apparently they are far more concerned about my brother, who most days doesn't get up in the morning. Things keep going wrong and I feel like there's nothing I can do. I can't believe the things I just heard from my parents' mouths. I got told not to slag him off, seconds after he was slagging me off and I asked him not to. Why does it feel like you can never win? Dad doesn't seem to think about what he says to me when we argue. He shoots right for where he knows it will hurt. Nice... coming from someone who is meant to always support me.
