^Agree totally.
I'm still having days like that where I'm just not really feeling "womanly" or "feminine," I just feel like the same old person I've always been, so I'm afraid that this means that I'm having doubts.
And my therapist told me, there's no such thing as "feeling female," which implies that you're excited about doing feminine things every single day. She said that she doesn't wake up every single day thinking "I feel like a girl today!" She pretty much never even thinks about her gender. Her gender is just something incidental, something that she's only really aware of during times where it matters, like when she's in a group of guys at a work event, or when dating, or things like that. Aside from those times, she's not even really aware of being female, she's just living her life. So much of gender is just how society treats you, and how you're expected to act.
The question that I always ask myself, which has kept me going through all of transition in spite of the doubts, is, do I ever want to go back? Do I want to see a guy in the mirror again? And for me at least, the answer is always no.
By all means, stop transitioning if you ever feel like you're wishing you could see a male in the mirror again, or would rather socially be male again. But if it's just a matter of not feeling "female enough" or "womanly," despite wishing that you could, then don't worry about it. Being female isn't something that you're going to be excited about forever. It's just a matter of living your life in a gender that feels right for you, to the point that you don't have to think about it anymore.
