Engine Started Making Noise While Driving

I was driving my car today and I noticed a light that said "O/D OFF". I didn't know what this meant so I told myself I'd look it up once I got back home. As I continued driving throughout the day, I noticed my oil light began turning on and off periodically before staying on permanently. Shortly after that I noticed my check engine light came on.

Now on my way home, I decided to take the highway, this is where the big problem began. As I neared my home I began hearing the engine give off a fast "clicking" sound(mind you i'm going about 50-60 mph). This sound got faster and faster as I pressed the gas pedal so I tried to ease off of it. And then I decided to go faster so I could get home before the car suddenly stopped working. Once I did this the "clicking" got really fast to a climax point and then the car jerked. I noticed that the car wasn't accelerating as I gave it gas and then the car slowly came to a full stop where I became stuck.

I tried starting the car again but it just did a fast clicking noise. What do you think could be the problem and what's the estimated cost to repair?
