Confuse and Frustrated

I'm in a indecisive position.
I dunno what I'm going to study in the very near future.

I'm torn apart by in between of three courses : Law, Psychology and Business Management

Law : As my family is not in a wealthy condition, my hope to study law in taylors seem to be very dim

Psychology : It is my second option after law, but not sure the career oppurtunities in the future.

Business Management : Seem to be a promising course but I'm not sure whether I have the will or interest to study it.
