Not getting into Oxbridge is not the end of the world; take it from a current student at Oxford. You might love your subject, or you might love the idea of studying at Oxbridge. Whatever your reason for applying, rejection might just be the best thing to happen to you.
I applied to Cambridge and was rejected. The next year, after achieving 3 A*s in my A levels, I was accepted by Oxford. I thought it was the best thing in the world, and at the time, I could not have been happier.
But after being here for a term (and a few weeks into my second term), let me tell you, it is not what it seems. Sure, there is the natural small fish in a big pond; all of a sudden you're not the best, you're lucky to be average. But that isn't what makes studying here difficult. What makes it difficult (I would say horrendous), is that no matter what you do, it is never good enough. And when you have to write 4 essays in a week on subjects you don't know much (or for me, anything) about, you find yourself in a very dark place. You fluctuate from having hope and motivation that you will be able to get by. But then you start the reading, and realise that you don't understand it, that you don't like your subject anymore, and there is no hope. You have to accept that what you hand in will be bad, that you will be brutally judged on it; that is hard to accept. It is impossible to deal with. So you comfort yourself by socializing, or watching netflix, or getting involved in too many societies. And that just makes the mess at the end worse. Having realised this, I find it impossible to even start essays. I will often just sit there, miserable, inconsolable, doing nothing. It doesn't make for a good end product.
It is a dark place from which there is no escape. And almost everyone I have talked to feels the exact same way. By the time you reach the end of term, you are sleep deprived, nutrient deprived, and often delusional. Nothing can be done about that. It is what Oxbridge does to you.
Not only that, but most of the time (especially in arts subjects) your tutorials/supervisions don't match up with lectures; you have to write essays for subjects you have never even heard about, never mind had lectures on. And if you're unlucky enough to have four essays in a week, due to bad and unorganised scheduling (which can't be avoided when you're dealing with world leading academics), you can't even begin to imagine the emptiness and darkness that brings to your life.
So please don't see getting rejected as a bad thing. Most other unis are actually better organised, and as a result your work will probably be better. You wont come to hate your subject. You will actually be able to have an enjoyable life. And trust me, I am not saying this to comfort you. I am saying this because I am so dejected and fed up by the whole Oxbridge system, that I feel a genuine need as a human being to warn people. I often wonder what my life would have been like if I had ended up at any other uni. I have forgotten what it feels like to have enough sleep, nutrients, a decent social life. All that is just a distant memory, and I am still only just getting by, by the skin of my teeth.
Rejection is probably the best thing that could have happened to you. And I am writing this as someone who has no history of depression or mental illness. I don't suffer from them. This is just what Oxbridge does to you.
I realise that it might be selfish and make me seem self absorbed to be moaning at being at such an institution. And I do appreciate the opportunity. I am grateful to have it. But it really is not all it seems. That I can assure you.
