Well at least your parents listened thats more then a lot of people on this forum.
For me personally its been almost 2 years since i told my mom and only a few months for my dad, and they live together heh. She didnt want me to spring it on him because she thought it would kill him. However after 2 years mom still has difficulty but accepts and loves me, she even uses gender neutral terms now, my dad still calls me him, but hes old and stubborn, what can you expect, he will take some time to get used to the idea.
My only advice,
Dont expect the world to change with you. People take time to absorb things, plus if you haven't taken hormones or appear like a woman its a lot harder to call you HER or your female name. Once you present your full time self, it becomes easier, i mean, before my dad saw me as a woman, i was disowned, but after (only a month later) when i went to pick something up at the house while i was on vacation, even he couldnt deny how much of a woman i was, and apologized. Heh, he still calls me he, but eh, hes old and stubborn doesnt bother me, if someone asks while i am with him, i will just say, he always wanted a boy, but he got 2 girls, hes just bitter. Then smile.
