Seriously, consider Architecture. It's very creative (see, e.g. Frank Lloyd-Wright's Fallingwater), but also requires techinical and mathematical skills (you've got a great grade in maths), and often requires art, which means that the pool of people who fulfill the admissions requirements is always fairly small.
Being an architect is also a great career.
Disclaimer: I'm not an architect and don't know any or want to become one, but I do know someone who does.
W.r.t. Psychology, the effects of buildings on people and people's perceptions of them is probably very important too.
