I'm a wimp pls tips

I have this bestfriend, I like her but I don't know if she like me back. I asked her if she dated anyone in our school and she said yes, she told me all their names. The problem is, is that they all have that clear skin, straight eyebrows, perfect teeth, and everyone talks to them. and im weird, i have pimples, cricked teeth, uneven stupid eyebrows, i dont socialize and i study alot. I really wanna know how I should upgrade myself, or if anyone have any, like, tips on how to make her like me pls tell me. I'm to poor to afford braces or expensive skin care where I live. I think she thinks I'm gay, idk. Help a friend out
