My basic rule is If you think you're trans, you are. The real trick now is sorting out where on the spectrum you reside which is often a moving target.
For many many many many, OK a lot of years I relied on what I call the 3D's; Diversions, Distractions, and Denial; to work through the dysphoria. I always wanted to be a girl since forever. At 6ft tall and balding since 16 it wasn't going to happen. Yet I tried transitioning twice in my early twenties. Both times utter fails. A lot can be attributed to my "Internalized Transphobia".
Thoughts of, or the "Dream", of transitioning someday was about the only dream that remained as I slowly turned into a lifeless, soulless thing over the years of doing what was expected. The decades of trying to suppress the dysphoria rather then addressing it
I had a lifetime of Shame and Guilt fed by the times I lived in. And TBH - No one wants to be trans. I hated my body, living in my body, hated just being different, being me. Seven years ago I needed to take the Trans-Beast on for real. I knew I needed to figure out how to get the female side to live in peace with the male side and not be beaten down.
With the help of a fantastic TG Support group, a couple of angels there especially when I needed them the most, some therapy, and plenty of reading and learning I began the healing process. At that time any sort of transitioning was not on the radar. No way, no how, been there tried it twice. I had well entrenched male existence that I needed to preserve. My sense of gender ID was just one aspect of the totality of me.
Today I pretty much figured out how to live in peace with myself. I have been able to balance all these conflicting needs and wants of my duality. I still haven't figured out where I am on the spectrum. I am thankfull most days I do not feel that I need to transition fully, only would like to. Most days living and presenting primarily as male works. Then there are the days that..... Still the risk of going full time can cost me more then I am willing to spend.
Only you can decide what sort of "Transition" you need to do. I transitioned, I changed a lot about myself starting from the inside, loosing a lot of the emotional baggage, the shame and guilt about being trans. Changed how I responded to conflicts. Doing "What was expected" changed to doing according to my needs and wants and those expected by others. In essence, I began to learn what it is like to Be Me.
