It’s very admiral to make the choice to raise foster children with challenges. It is even more admiral that you changed your thinking and actions. Many people don’t get it. Many people let the responsibility and stress fall on the caretaker.
I enjoyed your reflection of a difficult situation and identify the personal growth you have achieved.
Your writing is clear and concise. I would enjoy more insight and description of your personal relationship you have developed with your new family.
Thanks for sharing and best regards in your passion to be a writer.
