Honestly, I don't feel too different since I have taken hormones. Most of the classic personality shifts haven't really effected me. I've always been a very emotional and sensitive person, so there wasn't much to change in that department. And my thought patterns always seemed similar to other girls in my opinion. However, I have been told by others that I'm much more confident, open, talkative, and feminine since I have started. Personally, I think that has more to do with me feeling more comfortable with myself than a huge hormonal shift.
Having said that, there are definitely changes that have occurred, and I definitely relate to what you are saying here. For example, instead of feeling like a girl stuck in a boys body, I just feel like a girl. There is no longer a huge shame factor and now I feel really content and happy to express myself for who I am. I don't really desire to hide what I feel or to act in a way that I don't wish to. There is a sense of freedom and security about being the person I am. And I'm beginning to like myself and enjoy expressing who that is without fear or shame. Perhaps that's why others see a change and I don't. I've always been the same person, but now the real me is starting to come through (even if that's happening slowly and needs more of a push on my end). So, if that's what you mean, I can definitely relate.
