I'm 6"3 and a 17 year old girl and I don't think anyone will ever want to be with me because I don't look like a woman

What an absolutely fucking beautiful height. And what a ridiculous thing to think. If you want to look like a woman, then of course you do? Your femininity certainly isn’t defined by how tall or lack of you are. I have a friend who sighs with jealousy when girls with legs like yours walk by. Own it. It’s all yours. You are beautiful, you always have been, you just need to see it.
