Just Vent | Just Venting

So i just moved away from my family..pretty much across the country. I decided to continue college and earn my BBA. Well, it's going to cost 3,000 a semester for two classes...which is fine because its pretty much the only option I have. I told my parents I'm enrolling and will start taking classes in a month. Their response wasn't positive. Not only were they mad I was going back to college but they asked how Im going to pay for it. They pay for my sisters college and all her life expenses including rent, cable, internet, phone, and all that good stuff. WTF!!!! They help her with everything and can't even help me a little? I swear I'm adopted. I guess I should suck it up and get through life without help, like so many others do. I just feel like throwing my phone against the wall and screaming but I'm not. School sucks and its expensive.
