How about going to NYU and speak with a career counselor? Or getting in touch with a life coach to help you get on a path to success.
Also, i am not sure if you mentioned if you had a T but that could be helpful, as well. Especially if you are struggling with SAD.
By the way, I am a girl and I knew what I wanted to do with my career when I was 14. And my female friends are all very successful in their chosen careers...whether it be out in the workforce, full time mom or a little of both.
