This question is wild because before I transitioned to live authentically I legitimately never had a vision of my future self. Once I was about two years into my medical transition I saw myself in the mirror and the world stopped for a moment because I felt a wave of alignment and peace take over me. Now I'm teaching myself that I can have whatever future I create and I'm not limited to loneliness.
Gender-affirming medical care was the most crucial aspect for me specifically hormone replacement therapy and top surgery. Secondly ID and name change resources and support from NCTE. Thirdly trans support groups and programming through various LGBTQ+ centers and non-profits were huge for me.
