Those are 3 great reasons to write, and your writing is heartfelt, beautiful, and gives us deep access to such important struggles.
Your story is unique and yet relateable, in some ways, to a much broader audience. On the one hand, we can stay more “acceptable" to the norms of our world by erasing or burying our true selves. This keeps us safe but it is, inherently, a form of suicide. We dont truly exist.
On the other hand, we manifest our true, fullest selves in the world. At risk is facing prejudice, hatred, outcast, and harm, which is no small thing. The gain, however, is that we live. As the people we truly are, in a life that is truly ours.
Both paths are understandable, I wish you all the best on yours.
