When my friend found me in a dysphoric mess, told me she knew I was trans when all I could make myself say was some garbled cryptic message about thanking her, and my problem never being able to be entirely fixed, and supporting me. She made the phonecall to the doctors for me the next day to get me an appointment, went with me to it, and puts up with my pessimistic ranting.
My missus staying with me and seeing me as male even though we were together for a year before she found out I wasn't female.
Being called by my real name and being gendered correctly.
