I feel like I'm going through a break up because my car died today
Are you honestly feeling like you are breaking up with your car?
I'm heartbroken my car is broken
It is understandable to like your car and care for it, but you should not treat you car like a person and become so attached to it. Plus you should have taken better care of you car before it broke down.
You don't understand, I love my car.
Treating your car like a person is kind of unique, however it is not necessarily wrong. If anything, just use your car breaking down as a lesson to take care of your next car a little better.
