Essentially everything that would have told me a few years ago that my wish to be a woman was REALLY not something that cis-people experience and what the actual diagnostic criteria for gender-dysphoria were.
I was SOOO close to getting it about 10 years ago, it’s mind-boggling. Like I talked to other trans-people I knew at the time about how I suspected that I was trans, I read up on the topic and in the end stupidly decided that all my issues were only that I was lonely and that the only reason I wanted to be a girl was because it would have made dating so much easier and that that wouldn’t translate into dating as a trans-woman.
I mean, yes, this was a real problem I had, but there were so many other signs that it was not just that and I completely ignored that cis people would not respond to that problem with the wish for a different gender. It’s really as stupid as it sounds, and it cost me very dearly in so many ways.
