what you think about envy?

Hey girls, I'd like to know what you think about envy. Lately, I've been feeling envious, not in a bad way, but when I see girls who manage to finance their studies thanks to associations, donations, or scholarships, I really wonder what I'm doing wrong. Sometimes I start crying and get depressed. I just tell myself that I want to do what I love, but unfortunately, my efforts aren't enough. And I hear things like, "You have to be content with what you have," but how can I be content with that? I just want to study and succeed.
