Some unnecessarily condescending comments above. Clearly from people who have never experienced failure before, and the panic that comes with it. Some people have no shame in rubbing salt in your wounds.
To the OP: I think it's time to close the door on this and accept that you will have to move back to your home country, even if it's temporary. You know your visa is going to be cancelled eventually, even if it's still active now. It could be tomorrow, it could be months away, but it will happen when the visa office is informed. If you're still in the UK when it happens, it could get a lot worse for you. Better for you to save your dignity, take this setback on the chin, and come back stronger when you're in a position to start again. If you're still determined to continue, I would recommend starting the whole application and visa process again, perhaps returning to the UK in the future to start a course at a different university, or going to study in a different country. University in the UK can be pretty brutal for people for all sorts of different reasons, so there's no shame in accepting that it didn't go so well this time around. Make peace with this, return to your place of safety and security (I'm assuming you have family and friends waiting for you in your home country), and then come back again with a vengeance. I've been in your position before and run into many setbacks over the years, but I always come back stronger. If I can do it then you certainly can too. I wish you the best of luck and I hope it works out well for you.
