Ok I need some help.

I'm in my final year of my BSc in Economics. Although the year just started, I'm already panicking (well, mildly, but I can imagine it getting worse). That is, I need to plan for my future. But unlike many who go on to find a job or do a postgrad, I want to do another degree/diploma in the thing that I really want my life to revolve around -- Art.

I just spent about 3 hours looking through the various courses and schools of the University of Arts London, and well, I'm overwhelmed. One, by the sheer number of courses available, two, by the huge amounts of money international students have to cough up. Or puke out. (puke out sounds more dramatic so I'm gonna go with that.) [I'm currently leaning towards the Fine Arts degree from Central Saints Martin, the Illustration course from Camberwell, and the Fine Art: Time Based Media from Wimbledon.]

Anyone has any advice? As to which college is good (in what aspects), and whether a foundation year is a definite requirement (and if I can replace that with a portfolio, how amazing does it have to be?)

The other issue I'm facing is well..I guess more of an ethical issue. So my father has poured a chunk of his earnings into the current degree I'm doing. I have told him a million times that Economics is not what I want to do, and would avoid at all costs any occupation remotely related to it. Theatre was my other option, and to him, it has no future. I understand that he wants me to make a comfortable living (like he has), but I still can't get the message that that's not quite the kind of life I have in mind to him. (I understand that the last sentence is specked with naivety and grammatical errors.) But I really want to do this art degree..and get my life back into the right track. Doing Economics has been one of the most painful experience I had to endeavour..(i exaggerate slightly)..and I would like to avoid such a life in future. But doing this second degree would mean I'd break my dad's heart, waste his money, and I'll be asking him for much much more (at this point in time of my life, my financial status is highly dependent on my dad). Doing this degree means he won't have the high-flying career woman daughter he had in mind. And I'm gonna be annoying and whiney by saying that if I had to start working after I graduate to save enough money for this degree, I think I'll be stuck forever in this vicious cycle of survival and inertia.

Help?
