Is it normal i feel ugly even though the girls at work say otherwise?

Dont focus so much on your looks anyway. Thats what mightve gotten you in this situation in the first place. Looks arent the most important thing in the world.

America is just retarded. Unfornately girls are taught that their looks matter, when it's just that artificial thing that DOESNT matter.

Go for love. Something real. You'll be content.

Is it normal to have low self esteem? Yes, of course. But you have people telling you you're attractive so believe them. Plenty of people who feel ugly don't have that luxury of being told they're pretty, so you should believe it when people tell you that you're gorgeous. Even if you can't see it, be thankful that at least people see you how you would like to see yourself.

The exact same thing happen to me, the girls and my friends, even teacher in school always says that I'm handsome, etc etc. But I never think so and I never even have a girlfriend.. probably because i'm a weirdo+nerds+otaku+weak person.

Yes, I would say it's fairly normal. There is some humility to not believing everyone enough to let it get to your head. But you should learn to accept what people say. Next time someone compliments you practice saying 'thank-you' instead of turning the compliment away from yourself and on to another.
