I'm slim, I really want to be fat coz I feel intimidated?

I'm slim, not thin but just a bit below average. I'm 16, no doubt i'm pretty. I'm 5'5". In west Africa where i am, people appreciate women with boobs and ass a lot. Do u guys have any idea to gain weight fast apart from eating a lot protein and good diet and all that. I've heard that a million times but it doesn't work for me.
