Ella?
Sounds pretty normal to me. I can only compare to myself and what I have read of others. The big difference is that as of the beginning of me accepting myself, I don't identify as gay. However, as you undoubtedly will see over and over, gender identity and sexual orientation are not linked. I know of many MTF people who have gone from not desiring men before transition to changing their orientation.
I have found my dysphoria much more easy to identify now. It is actually cool in that I can now recognize the difference between dysphoria and just a bad day. In a way, I think accepting has made the yearning to change stronger and that can lead to dysphoria fairly easily. I just have to remind myself from time to time that I am a person not just transgender and a series of symptoms. Sometimes we can forget about it for a day or so.
I am not yet on hormones. I am taking baby steps that most people won't/can't see yet. However, yes, much more emotionally free. I am happier and nicer. I get over anger easier. I am able to see a situation that is bad and realize it is not all from me and that there can be light in my future. My SO has noticed most of this. That is part of why I think she has not run screaming away. Also she does love me and saw how much I was depressed and hurting.
Don't know if that is helpful but for what it is worth. I have read of a number of MTF members who have stated that they started off gay before realization. I will let them speak to your other questions as well as the ones I touched on.
Welcome to Susans. I hope you have a pleasant stay and a smooth journey.
With warmth,
Joanna
