Part 3 is fast-paced, which is a good choice for this portion of the story. Your details are well selected to express the urgency of this harrowing experience.

The final sentence is excellent, fading out of the scene with an indication of what is to come.

I have just a few minor revisions to suggest for flow:

First paragraph, Second sentence
"We had many plans, including continuing and finishing college."
Mentioning college and school within the same statement sounds a bit redundant; simplifying the sentence so that the two verbs refer to a single noun solves this redundancy.

Second paragraph, Second sentence
"I would drive Ken to work in the morning, then I would return home and collapse on the king bed to sleep until...."
I feel that "lay down and collapse" are similarly redundant. Trading "lay down" for "return home" solves the redundancy and also enhances the flow of the narrative by clarifying that after taking Ken to work, you would go back home and sleep. I also feel that three "and" statements here is too many. Swapping the last one out for "to" helps the sentence to flow better.

Fifth paragraph, Third sentence
"Dr. Jones said...."
I think that having "said" here helps this sentence read better. If you're concerned about having too many "saids" in a row, you could also swap out the following "I said" for "I told him I would go...."

Tenth paragraph, First sentence
"The doctor came....but I wasn't very aware of things then."

Once again, a very enjoyable read that keeps me looking forward to the next one.
