Dude, let me give you some advice. I have a friend, let's call him Bob. He balded at 17. He was very insecure about it until he was 24. Then he hit the gym, worked on himself and his career, and focused on himself. He began to get swarmed with female attention, now has a fiancee and is to be married. He's not even that tall.
Confidence will take you far my guy. Working on your health will make people see your value. You can do it.
