Seriously...seriously?

Ahhh! I am the only one who cleans up my messes in shared parts of the house. My room may not be the cleanest at some times, but that's my room, and nobody else really goes in there. When I shower, I pick my clothes up off the bathroom floor. If I trim my hair, I clean it out of the bathroom sink. If I spill something in the kitchen I clean it up. Twice I stepped in cereal going to the back door in less then two weeks...maybe less then one. I just went to the bathroom to find facial hair in the sink. There are always clothes on the bathroom floor, and when Donald, Bryce, Nathan, and Ryan shower they all always leave their towels on the floor also.
I ugh, I don't really have friends over because my family is sloppy, and I think my house smells weird. I don't want to have friends over and have them have to go to the bathroom and go and see my mom's underwear or bras just sitting willy nilly on the floor and shit. Or see Ryan's pooped up underwear on the basement floor by the washer...uh ew. Since we got our dog, and he's not house broken quite yet, we have a mop bucket and my living room smells like dog piss. Sometimes our kitchen smells weird because nobody takes care of left over food, unless I do..Fish is the worse.
I'm so tired of this, and when I tell my mom about it, she goes "are you going to clean it up?" uhhh omg? what? I clean up what I'm willing to clean up..NO I 'm not going to pick other people's clothes off the bathroom floor, no I'm not going to clean Ryan's poop underwear..No I'm not going to clean up other people's messes!!! If you spill cereal how hard is it to clean it up seriously?? If you shave your face how hard is it to clean most of the hair out of the sink?
How hard is it to take the garbage out when it's full? Why am I the only one who does this kind of stuff?? Well, without being told, and when I'm told, without crying about it. Ack....
