Too much pressure not enough help?

Alright, after graduating high school I decided that I was going to work a bit to make money for college easier for me. My step dad wanted me to go directly to college, he didn't like that. So he cut off my phone. This is just complicating things, because now I have to rely on the home phone to call colleges and get information and receive calls from them. Everyone in the house constantly uses the home phone. I got a job but I quit because I was coming into contact with sulfuric acid and they were going to have me drive a big payloader. (I have a phobia of even driving my car.) I'm trying to find another job. At the same time my grandma (who I'm currently living with) is really pressuring me to get into college and making me feel guilty about it even though I'm trying. Neither of them will be helping me at all, I'm relying on financial aid, which is difficult for me to attain because of all the stupid forms that I don't understand. The college I applied to also I guess "forgot" to send information to me even after I called them three times so I'm absolutely clueless. I tried explaining all this to my grandma but she just doesn't understand. How can I get her off my back?
