So...what exactly is going on here?

My financial support is raised in Pounds Sterling (GBP).
Sterling is currently the third-largest reserve currency, after the US dollar and the euro. The pound sterling is the fourth-most-traded currency in the foreign exchange market after the US dollar, the euro, and the Japanese yen.

However currently...This is not good. When I arrived in California a year ago 1GBP = 2USD. It's like getting a sudden pay cut for no reason whatsoever!
