Knowledge is The Key
I'm not writing for girls, because, being a boy (and man) myself, I feel I cannot know in detail what girls need to hear. I will write what I know about girls and women for my audience (boys), and I trust that knowledgeable women will write the books, essays or online documents that can help girls in the same way.
Please do what you need to do to be well, and to be happy. Best of luck.
