Frankly, I think questioning ones own nature in a productive (not self-destructive) manner is a good thing. It's how we find out what we really are, what drives us, and what will lead to our being happier in the long run.
We all question, we explore, we seek to know ourselves. Many here on this site came to conclusions about our true nature only after many years, or decades of effort. Many others who asked the same questions about themselves undoubtedly came to other, different conclusions. Some didn't like the answers they uncovered and stopped searching.
In my case, I didn't have much about my childhood that I wanted to remember. I had walled off the more unpleasant parts, leaving me with a few happy memories and some huge gaps. I spent my later teenage years in an angry haze ("Vitamin shots, so you'll grow up right." Thanks for the testosterone shots, Dad.). I joined the military, because what's not manly about lethal weapons and huge deadly machines?
I didn't ramp down from the T until I was in my 20s, and even then, I didn't consciously realize what was up until I met a transwoman in my early 30s, who was interviewing for a job on my team. She was having a rough time passing after our all-day interview process, but I tried to respect her as a person looking for a position with us. I found my self thinking that she was doing something pretty darn hard, but I still wished I could do that. Wait, what? Where did that come from?
That started me on my own path of questioning myself. I figured out my true nature, but buried her deep as I now had a wife and small children that coming out would cause grave problems with. That lasted almost 30 years, but I didn't quite make it to the grave with that secret. (See avatar...)
Those buried childhood memories started bubbling up from the mental swamps a few years ago, bringing anxiety, dysphoria, and depression along for the ride. I needed and got help, came out to family, and and preparing for a big transition.

So Jayne, keep asking questions, and look deep at the possible answers and paths open to you. I sincerely hope that you'll find a path that leads to your long term happiness, wherever that lies.
