Hi,
I'm so sorry you're feeling like this! It sounds like there's a few area of uni have turned out not a expected- course, friends, workload. I would advise speaking to your parents and your academic advisor at uni, or using the drop-in service at your students union! Friends and downtime are very important, especially with such an intense course. Do you currently study with friends, or alone in your room? I understand it can be hard to focus with people but the social activity of studying together and then having lunch together gives you time to chat, and gets you all into a routine of being up and at the library early!
