poor dead car

My car died last night. I had the 2 a.m. shift in the prayer room. The engine sounded bad on the drive there, really high-pitch and strained, and the car was super sluggish. After my shift was over the car wouldn't start. So I slept in the prayer room and in the morning it was fine. I drove home to get breakfast and when I tried to go to work I couldn't even get the engine to turn over. I think the end is here. My dad told me awhile ago that one day soon it would randomly quit on me. I was hoping it would wait awhile longer.
