can't

I like this piece of writing, not positive that you are going for poetry or not, but I like it regardless. The repetition of the "can't" lines is quite effective. Each stanza has something that catches my eye. I can't make the first or last work yet, but here's roughly what I'd like to do:

Pulling into the parking lot,
I wish I was anywhere but here.
I can't get out.

Coming up to the doorway,
my feet heavy with despair.
I can't go in.

Walking in darkness with my eyes closed,
I see a stagnant life.
I can't continue.

I think the first and last need to be in there but I'm not sure how to reword them in the style above.

Bonus points to Pacho for being poetry-focused and not expressing any sympathy. ;)
