Hi friend! I just wanna let you know that you are loved, and that you deserve to experience the good parts of the world! I know it's hard and it feels hopeless, I deal with these thoughts too, but just keep surviving until the thoughts aren't as loud. Stay so you can keep doing things like eat your favorite food, listen to your favorite band, feel perfectly cozy in your bed, play your favorite game, find a new hobby or show you like... stuff like that. I believe in you <3
I would personally go by what the wikia says. The page doesn't say that cis people can't use it, so I would say that you're alright :) Glad you found a label that feels right!
