I Have Family Members That Get On My Nerves

So, due to the fact that I work so much, I don't have time to do my homework. Or when I do, I'm too tired to get it done. So I asked if I could drive myself to church and then come home early to work on it, and my dad said "No." and said that I had all week to do it and that I should've done it earlier. I'll admit, I should have worked on it a little more, but either way, I needed the extra time to get it done. Then my dad started saying how "God needed to come first." And things like that. Then he said that if I didn't get my project done, he'd force me to quit my job, which I said he can't do because I am an adult, then he said "there are other ways to do that." When I asked how he responded "Well, you would get kicked out." And when I started sobbing he told me to quit it. My mom made him backpedal and he said he was simply "making a point." And that "he wouldn't really do that." But it just pisses me off. Why say it and make me all upset?
