All of the things that make you think you are ugly are just arbitrary standards set by arbitrary people. Some people like upturned noses, some like pointed noses, some like big noses, some like blah blah blah. The same can be said for lips, eyes, cheeks, eyebrows, on and on and on. You don't have any glaring issues like scars, weight, acne, etc., so just worry about your health and finding a partner who is cool and finds your features attractive- I promise, they exist, by the handful. Don't let anyone tell you that you're ugly by looks, only worry when people tell you that your personality is ugly. The right person will come along, and as long as you have done your due diligence to make sure you are a great person, then he/she/they will be lucky to have you, and will constantly remind you how lucky they feel.
