trans | question

are there any usable resources that could be used to educate others that is geared towards those of us who didn't really exhibit cross-gender behavior as a child?

i knew i was a girl at 16. came out at 22, and even after having been on hormones for.... 1y8m3w4d and progessing with my transition, i still can't be taken seriously by my parents. their arguement over and over is 'we don't see it, you never acted this way when you were younger'....

i.. just donno what to do.
