Hi Victoria,
I understand where you are coming from. I have learned that if you want something go after it guns a blazing. It sounds like staying where you are is bumming you out so much that if it gets worse your studies could suffer and you may actually end up staying there much longer. I would suggest maybe completing your linguistics degree overseas? Could you possibly take a summer class in London? You would be able to get a taste of London without the commitment because I agree with Ahlive that it might not be all it was hyped up to be. I also have dreams of moving to London or moving abroad. Can’t wait to get out of this two bit town! I hope that helps my dear.
