I had a sister in law who was more than 6 feet of height, with bigger hands and feet than I have.
She was such an adorable woman and to be frankly, she was very elegant.
It's not hand or feet, it's how you are, how you present yourself, your behaviour, your voice, all these things makes you womanly.
If you are sure you're a woman than be a woman, you don't have anything to hide, like hand or feet or whatever, just BE a woman, that's enough.
So, safe yourself the trouble of thinking about suicide, there is no need for it, don't think about the stereotypically picture of a woman, small, everything is little with a high pitch in the voice, there are plenty of women who don't pass in that picture, so maybe you're one of them, that doesn't change the fact that you can be very womanly.
Does this answer your question?
I truly hope so, coz people do have more possibilities than they think.
