Reference

Based on my search results, I found two potential sources related to the topic of Joanne being released from the hospital:

1. A memoir titled "By Accident: A Memoir of Letting Go" by Joanne Greene. This memoir details Joanne's experience of intense pain while in the hospital, her desire to be alone, and her panicking in the absence of her husband. However, this source does not directly address her actions post-release from the hospital (source).

2. Another source mentions a Joanne Kruchten, who, while recovering from multiple surgeries and unable to walk, expressed a strong desire to return to running, which she loved (source).

These sources discuss the individuals' experiences related to accidents, but specific details about what Joanne does immediately upon release from the hospital remain unspecified. If you are referring to a specific literary or fictional character, please provide more context or identify the work to better assist you.
