what is really in Aarti's mind???

i didn't understand why she wants to hide from Yash after seeing him on bus stand(in precap)??? it's so obvious that he is searching for them only...then, now she knows that he wants Aarti back in his life then why she need to run away from his life??? i am very angry on Aarti😡😡. why she wants to commit suicide when she knows her health condition very well???
