Is there an inner core of your gender identity that never changes?
Your moods can change like the weather, your environment can influence your focus, thinking thoroughly about a difficult decision can make you find so many conflicting perspectives that you don't know any more what is right.
But is there something inside you that is not touched by all of this, that is always there, always the same, always yourself? Concentrate more on that which is timeless, accept that life can be confusing, but know who you are deep inside.
I have made my decision to transition without any help from anybody, I did not want to be influenced in any way. When I had made the decision, I went to an experienced psychiatrist to get my HRT referral, and of course they tried to make sure that it was right for me, but they saw quickly that I had done my homework and supported me in every possible way. At that time I learned about the various kinds of trans-ness for the first time, and I found it difficult to identify myself with any one completely.
Had I known about non-binary, genderfluid, demi and whatever categories there are, it would have made my decision more difficult, because I would not have been able to find the right one for me. Instead I focused on my deep inner self and on the thoughts and emotions that had been with me all my life, letting them guide me.
My mind had created a lot of obstacles for starting my transition, my heart had dreaded the pain that it might bring, but in the end I have listened to what my subconscious self had been trying to tell me all along.
