In real life i think that somebody that is going through what Alya is would look rough.
Let's face it. She is grieving for the sudden loss of her father, feeling guilt at betraying her religion and boyfriend by getting drunk and sleeping with his friend, worried and scared about what will happen if he and her family find out and now she is being physically sick too, causing worry that she is pregnant.
A half decent actress and make up department would be able to convey that.
