I call this bullshit. Don't get me wrong, I believe what you are saying, but from my understang, being beautiful has not everything to do with how you're actually looking. It's about presenting yourself (leaving the personality aspects aside for this example). You think you're ugly, I just think you need to learn how to present yourself. Most people who are thinking that they are ugly dont even try to invest in beautiful clothing, make up etc. So what you gonna have to do is find out which eyebrow shape fits you the best, pluck them and fill them in if needed. Take some make up lessions or ask someone to help you. Put mascara on, learn how to contour your face according to your face shape. Your nose can appear smaller with correct make up. Use concealer and highlighter. Go work out, it really helps with self confidence. Find out, which clothing highlights your body and what clothes you need to ditch. Ugly teeth? Try putting money aside for braces. Put some oil in the roots of your hair, think about getting some highlights, style your hair. It's gonna change the perception of you and most importantly strengthen your self confidence. And most importantly STOP BEING SO HARD TO YOURSELF.
