This was a fun read

'I felt myself wake up, kind of.  I was more asleep than awake.  I tried to wake up, but I couldn't pull myself up.' - I like the desperation of this, but the repetition doesn't quite work.

'I tried to make my form, move just a little bit.' - perhaps body instead of form, and remove the comma. Also, in the next paragraph, perhaps put 'Trying to move hurt like fire in my veins,' here instead.

'Our car struck the median wall' - wrong tense, as the accident has already happened.

'Our car is an accordion of death.' - I like this description

'I kept getting hotter and hotter.  I am slowly…' - watch for changes of tense.

'It's a long trip through the light…' - I feel as though this paragraph could be expanded upon with her emotions and thoughts.

'The Devil stretches his arms wide…' - Perhaps describing him in the creepiest way possible would sound more sinister? 

'You'd think hell would be one giants fire pit…' - again, show don't tell. Have her walk around hell, perhaps even have her learning about the spikes by treading on one?

'…even though I know have boils all over. - What do they feel like? Look like?

I really like the ending, as though she has a second chance. I would have liked some little clues as to what she did that caused her to end up in hell, but overall it was an interesting take on it
