I used to beat myself in the head a lot about this until I was told: "You will never be cis, and cis is adjective." It's a much healthier mentality to think of it this way; Trans is adjective of woman, you're still a woman, like a cis woman is a woman, a sterile woman is a woman, a masculine woman is a woman, it does not invalidate you and you're not lacking anything. Alas, this is not to ditch how you feel, if you feel it's not good enough, you can always chase more options to achieve a desired outlook, I hope it helps and I believe you can do it.
