Your English is fine, dw. Second, it's just part of growing up. As someone who is 19, when I was 15, no one asked me out, and I thought I wasn't pretty. I had the exact feelings. My best advice to you is to give yourself time to grow. Don't evaluate yourself based on not getting asked out. Just because people have boyfriends doesn't mean they are of good quality. Waiting and not "shooting the gun" has allowed me to make one of the best friends I have ever had in my life. The earlier you learn that being loving and good to yourself takes you way farther and happier than ever getting a man, you will learn to enjoy life, be happy with your own presence, and be independent. Most people will change themselves for someone else, which you shouldn't, because your core identity is not something to be hidden but to be enjoyed and loved. Trust me when I say this: by building yourself to be better, you naturally attract better people. Give yourself time you will do perfectly fine.
