What's wrong with my car

I'm 17 I don't know much about cars I just bought my first car it's a 1997 Honda Civic lx, it overheats and the first cylinder has little oil drops in it. Little drops of the oil shoots out of the hole where you check the oil from. And the car turns off when I take my foot off the gas. The whole car shakes while the car is on in park. The oil is very dark dark dark brown almost black. I only work part-time so I can't afford to buy a new car. Some people are telling me to fix the engine other people are telling me to just buy a whole new engine. I need advice from other mechanics so I can know which one is worth it.
