i dont know you, i dont know your situation, but it sounds to me like stuff at home isnt so great right now. your parents are probably stressed out themselves. they've got bills, responsibilities, crappy bosses, and stress all over the place. i'm a mom myself and sometimes i'm not as patient a person as i ought to be. this being an adult stuff is harder than it looks. yes your parents should be there for you, but they arent mind readers. next time, maybe try something like "i'm having a bad day. can i talk to you, when you get a minute?" i know that would get my attention. people tend to be very stressed and busy these days, and very rarely do we try to see different points of view. try to talk, and explain how you feel. if it doesnt work, try talking to another adult in your life, like a teacher. good luck.
