Depression During Final Exams

<p>Last Monday I wrote my 2nd final exam of the semester and I have been feeling depressed since the moment I handed it in. The first few days after that it was really hard for me to get myself out of bed. Then, I tried going to the library but I just couldn't focus there and I just felt really scared being in that environment, even though I used to spend most of my time there before all of this happened. Last night had a panic attack and spent hours crying non-stop until I just didn't feel anything at all. My family is on vacation in another country and I don't have anyone to talk to. I haven't been able to focus on studying and I still have to write 2 exams on Tuesday. I feel like I am probably going to fail at least one of those two exams... If that happens I will probably fail the semester and I will have to kiss good-bye my dreams of getting into grad school. I don't even care about writing the exam anymore, I feel like there is no point. What can I do? Do you think that talking to an adviser at university on Monday will help me at all? Do you think this is a good reason to apply for deferral?
(sorry if this was too long, I'm desperate)
Thanks in advance</p>
