Either way, this jump is disturbing, but the description likely caused you to cringe more than the summary. And doesn't some part of you want to know what happened next? Who came to help? How quickly they reached a doctor? If all had turned out well in the jump, you would not have the same compulsion to read on. If you can't think of any details, write a line of summary and return to fill in the details as you remember them. If you remain relaxed about it, you will remember. If you don't, you don't. Writing an autobiography isn't easy, but it should be enjoyable.
Take steps to self-publish your book. Even if you don't want to worry about trying to sell your book to the public, you might want to have it designed and printed to keep for yourself and give to your family members and other people featured in the book. Research companies that offer book designing, printing, and shipping services, and decide how many copies you'd like to order. Many companies offering these services produce books that look just as professional as those printed by traditional publishing houses.
Develop a central theme, main idea or thesis that clearly explains the purpose behind your autobiography. For example, your theme might be about how you overcame obstacles to become a stronger person, or it might explain why a particular passion -- such as mountain climbing or rescuing animals -- is so important to you. Back your theme with details and background information about your life experiences. For example, you might explain that your dad is in the military, so you've had to learn how to adapt quickly to new schools and unfamiliar environments. Or, you might discuss what it was like growing up in a poor, single-parent home, but how your family was always willing to take in injured or stray pets.
