My 5 years BS/MS application

When I was in the Hong Kong airport, I checked my email and realized that I finally get a reply for my 5 years Bachelor of Science\Master of Science application. According to the email, I was not recommended to enter the program. I feel so sad. Maybe I need more time for my master program since I still don't know which field I should focus on. I remember the adviser for the program suggested those whose ultimate goal is to obtain a PhD not to choose to take the 5 years program because there is no point rushing through the master program if you wanted to learn more. Now, I am lost. I don't know what should I do. Maybe I should try applying for the ordinary master program.
