Same here, to be honest the person diagnosing me was looking for allllll of those signs but they didn't really exist. I hung with the boys but I was still always the girl even if I saw myself as a tomboy.
The only sign I had is that when I started to explore it, I finally felt happy for once. I felt really guilty about that happiness at first, but I felt so much joy, it was too big to deny that I was along the right lines.
I just felt right for the first time.
