I am sorry to say there are only two options to change the shape of eyes, Cosmetic surgery and makeup. You have to select one out of these. From my point of view every eye is beautiful which can see. Look at the peoples who have eyes but can not see.
The reason she might have look scary was because when you get used to someone with makeup once they take it off you will not be used to the natrual way they look.
Shape your eyebrows it works
Just rub your eyes a lot
