Buy a trans flag and hang it in your home, left wrinkled of course ;)
I know exactly what you mean about not having a choice. That is what sealed the deal for me. When you're willing to take on the long scary journey that is transitioning, especially as AMAB which involves giving up lots of privilege in the process, that is kinda the point of no return.
Fortunately for me it has not been anywhere near as bad as I feared in the worst case. In fact it has been such a wonderful experience, I have a lot of hope for 2024, my third year of transition.
good luck Amelia, and don't be afraid to lean on us for advice, we have to look after eachother.
