Climb it.
Seriously, don't give up. Think positively. You've got a few weeks left to go. All your work will be for naught if you give up now.
You need to look at the heart of the problem. Have you been doing too much study with minimal results? If so, change your study technqiues. I hit this so-called 'wall' in the first two weeks of holidays but I think I'm over it now. I sat down and wrote up a little plan for my self which involved many small portions of revision such that it amounted to a lot, but was varied and in small amounts such that I do not get bored and lose concentration.
Also, part of my problem was that I needed 99 (and really would still love that). Do you have some goal UAI which most of your plans hinge on you receiving, but which you aren't gaurenteed of achieving? If so, you'll need to covince yourself that there are other EQUALLY VALID options and paths for you to follow if you do not get that UAI. Othwerwise you'll probably end up being nervous and worrying about it all the time, which can culminate in this brick wall feeling.
Each person reacts to the HSC and its various stages in their own unique way. So unless you describe your problem in a little more detail, the level of support you receive will likely be minimal (more likely communal sympathy where all the other people who've hit a brick wall bitch and moan about it
)
