Thank you for the opportunity to help you with your question!
(1)according to my views, because Maria was the first one in the family, along with that shy natured ,obedient girl.She thought that to help the family and parents is her first priority.She never realized what are her interests.She thought that it his her first priority to help her parents in their family business, this family business was not her ultimate goal, in the beginning she could not realized, she just thought for her responsibility.Also her parents did not help her in finding out her interest, it was their mistake on their part. That job was not up to her caliber.Her capacity was more which she realized later on, and that's why she fell sick.So counselor did the right thing and found out her real interest and advise her to study furthe.
(2)Maria had problem in making decision because she is shy natured girl, lack is self confidence that is why she could not decide what to do, she could not find out what she likes to do, she just thought for her responsibity as first Bon in the family and joined the business.
Please let me know if you need any clarification. I'm always happy to answer your questions.
