<human>: About 4-5 weeks ago I graduated from university with a good grade and got a place at a highly-respected London uni to do a one-year Masters course. Besides the financial costs I was hopeful that I would be able to perform to their expectations.

Recently however, I'm losing more and more confidence in myself every lecture I go to. I had one today which, quite frankly, went completely over my head; I felt as if I had learned nothing and came out feeling worse with myself than before I had gone in. Everyone else seems to have something to contribute to the topic at hand, something to discuss or points to add, yet I'm struggling to even comprehend the first few buzzwords that are thrown around ten-at-a-time.

I don't want to quit, I would hate myself for doing so, yet I'm terrified that between this and two jobs, I'm going to have a meltdown sooner or later. Is there anyone who is/has been in such a scenario who can offer advice?

Thanks
