I'm not that good with feelings either but personally I think people will feel better if someone told them "You're not ugly, you're beautiful and even if you were ugly, me and many other people would still love you because if you look ugly but are kind on the inside, youre pretty. If you're rude and obnoxious on the inside, no matter how beautiful ...... 1 reply
I'd say something to make her learn that beauty doesnt equal your value. Everyone also pervices beauty differently so everyone could be the most beaitful person to someone but the ugliest to another no matter what. Don't make her feel like she needs to be beautiful or told shes beatiful to make her self worth go up. She needs to learn herself early...... 1 reply
I am also not good with emotions, especially people crying, but I think you can indirectly apologize? You know like buy her her favorite candy, write her a "my bad" sticky note, or you can bring it up causally and explained to her that you didn't mean it like that. Idk if that helped :/ 1 reply
