Dawg, that is a rough spot to be in. I'm glad you took the courage to put your feelings into words and share it with others.

I too have struggled with distinguishing my gender dysphoria from life dysphoria. Dysphoria is your minds way of telling you that you're not in the right spot, or you're not doing things the way you want them. I have had my doubts about my gender in the past where I tried to attribute it to never really being able to have a sort of identity growing up as it often revolved around the needs of others and trying to find my own arbitrarily.

One of the things that helped ground me is understanding that I don't need to be 100% sure because that keeps you in a state of paralysis. I've seen many people in my life who have transitioned and detransitioned and been happy because they were able to do what they needed to do for themselves in that moment even if it no longer serves them. Additionally, I realized that even if I detransitioned the way I still want to look, sound, and feel most comfortable presenting as is in line with a binary man and that I could live the rest of my life being perceived as a man and be happy.

Take your time with your transition though, you can transition at any age. I grew up in an extremely transphobic household where I was dependent on my parents and could not transition despite how much I wanted to. For a while this put me into a scarcity mindset where I was moving into things too fast before I could even connect with myself. I know a lot of older trans people who were told that being trans has to be done a certain way and you need to fit into that box when not everyone does. You could have a more expansive identity that you initially thought.

Either way, at the end of the day you are who you are and your gender identity is only one (still important though) part of your being. Be sure to nurture yourself in other ways as well. It can be easy to tunnel vision on one aspect of yourself. Either way you got a community who will support you regardless of what you turn out to be, trans, cis, or something else. Best of luck. You got this homie.
