Good to hear your happy man.
Personally I feel some gender euphoria but not happiness. Idk, maybe I do but I'm too emotionally brain dead to even know my own emotions.
Why am I feeling euphoria?
I casually dressed like a satanist (it's just my varsity jacket that has a pentagram on the back and front and my t-shirt that's the Dragon sin of wrath, not much of a fan of the 7 Deadly Sins anime though)
