I know the OP has responded negatively to every suggestion... and honestly, the suggestions given have been really wonderful. But only when the OP is ready to listen and take them to heart will they even potentially do any good.
That being said, let me throw a few more into the ring.
First of all, you will never be treated by others any better than you treat yourself. Meaning, if you continually disparage your appearance and say that it's impossible for anyone to see you as a female... you're creating a self-fulfilling prophecy.
It starts with you. You need to get to a point where you're ok with how you look. Where you see you as the unique woman that you are. Women, after all, come in all different shapes and sizes. Sit down in a mall, or park, or anywhere where it won't be to creepy and people watch for 30 minutes. You'll see all manner of looks of woman all up and down the so-called masculine/feminine scale.
And once you're ok with you... you just have to go out into the world with confidence. If you feel like every one is looking at your judgementally, you'll give off that vibe and people will start to, well, look at you somewhat judgmentally. But if you just live your life? People will just live theirs. They might notice you for a split-second. They will pick up on your clothes, your hair, your makeup, or some feature and make a judgement. Some will make a judgement that this person clearly wants to be treated a female and treat you as such.
And for those who see that and STILL treat you otherwise? There's a special level in hell for them. Feel an ounce of pity and move on.
I guess what I'm saying is, you first need to see the woman you are in the mirror...flaws and all. And then bring her into the light.
Love,
