I probably can understand how do you feel, though.
No one's saying that you are searching for sympathy, I'm glad you are able to speak out it at least here.
I have been suffering from depression too, however it's been almost a year since I have overcome it. But thing is, I still suffer from outcome. I still have procrastination and concentration problems, but I wish to help you as much as it is possible.
You should speak with person that you trust the most or even cry your heart out, because the emotions need to be let out. Then take one day or two for a complete relaxation, clear your mind from all the worries, don't even try to think about university stuff.
When going for a work, you should hide/turn off all the distractions that are possible.
Myself, I'm trying to do this as much as possible as I have finals coming up.
Plus, you should really talk with your tutors or someone that is responsible for your studies about your mental health, don't ever try to hide it, they will have to understand it.
If possible, it's good to visit a psychologist or therapist (I'm not sure how people call them in the other countries) and they will issue the medication or treatment needed.
As one person mentioned above, exercising is one of the best things to fight the depression. Jogging/cycling in the parks or somewhere in the bare nature helped me a lot. Or swimming. It is just something that puts you off from the thinking for awhile and gives your brain some proper rest.
About your work that you have for now, everything is possible. However, you must not overwork yourself, try to divide the homework/studying/sleeping time fairly and don't let yourself to run away from the schedule!
I don't know, if I was able to help you or give something useful, but I hope you will be able to fight this well. Feel free to ask anything though!
