In the UK we have something called "mitigating circumstances" that you can apply for, and which you will definitely be granted if you submit sufficient medical evidence. I have done this so many times now it isn't even funny; first you submit a claim so you can try to finish your assignments over the summer, and if you can't there is the option to mitigate again and spend another year on it, in which case you can attend lectures again and all that (if you have missed out on a lot of them due to illness, as has been the case for me). With mitigation you don't have to pay tuition fees again, so for the past three years I have not paid anything, so that does not add to the stress (though in my case fighting with the Norwegian Educational Loans Fund has been less than hilarious).

I'm going to have to apply for mitigating circumstances again this summer, but hopefully I will be able to finish by August. I don't think I can handle another year, and will most likely just quit if I end up being faced with that. The very idea of that is soul-destroying, but it's not the end of the road YET.

The same applies to you. You are still young - quite a lot younger than me, as well! I'm 27, and still don't have a BA, but you know, I'm still trying, and so can you. Spending an additional semester (or even a year) on your degree is a MUCH better solution to your current problems than what you are suggesting. I understand that you are scared, and I feel for you, I really do, but please talk to your counsellor at university. Or your other psychologist. Or BOTH. Tell them everything you are experiencing.

And I know this is easier said than done, but don't worry about what anyone else will think if you ask for some time off (which really might be the best thing for you to do at this point, even if there is a "mitigating circumstances" alternative available to you). Your life is WAY more important than your parents' opinions and their potential criticism, which is the worst case scenario. Your parents, hard as it may be to believe right now, most likely want you alive, and would prefer that over you driving yourself to an early grave. And if they don't, well sod them! Like I have said in the other thread, it's YOUR life, and you deserve to live it, and live it well.
