The reality is that there are a lot of plastic surgery procedures out there - nose surgery, jaw surgery, chin surgery, brow surgery, cheek surgery (bone and fat), hair transplants, ect ect. Then there's laser hair removal, form-fitting clothes and wigs (clothes and hairstyles designed to put less emphasis on tall, broad, or thick women), make-up, and even glasses or big hairbows and hats to put less emphasis on a large face. With enough money (the big problem), I've always been convinced that improvement is possible on literally anyone. Hormones feminize the skin and take care of oil and acne (and slowly stop hair thickness/balding). There's a lot of changes out there.
I mean, I think I look like a monster, but I can see very well what my face would look like with FFS and I believe in it very much. Sometimes the line between male and female is not so obvious, and like with my own face, I only want minimal changes (just a nose and brow surgery) because I've found plenty of beautiful women who resemble what I will look like with those features. I haven't found any women who resemble what I look like now (and men-wise, only ugly, nerdy basement men, like Jack Black), but with just a bit of surgery, I believe small things can do revolutional changes.
Now, maybe you need the whole Extreme Make-Over, or maybe you need to find more examples of women who you would resemble after a few smaller changes - either way, without even seeing you, I would say improvement is 99% of the time possible, and if you don't even fully pass, it can be more about expressing your personality, surgically achieving softer features even as a man or woman or androgyne, so that your personality shines through more realistically. I believe there's always something "closer" to the goal than what you're feeling like now, and if you post pictures, someone may be able to give some advice on specifically what changes you may need.
