It's a very popular idea nowadays that gender and sex are completely different things, independent of one another, existing on a spectrum of sorts, where you get to decide where you belong, and it's disrespectful and hateful if other people don't agree with your self diagnosis of what or who you are.
Hating yourself does not mean you have the wrong body. Changing your body or appearance will most likely not remove your self-loathing. Neither will forcing people to support your lifestyle.
To truly find happiness, you have to find a goal of who you want to be that stretches you, takes you out of your comfort zone and grows your character. Being comfortable is not a meaningful thing. Self improvement is.
Thank you for your time.
