Sometimes one just has to push themself. Damage control is important. As much as it may seem you may need a "break" now and then, are few weeks off really worth a lost academic year?

Been there, done that, they aren't.

Priotize and need what needs to be done and postpone what can be postponed... but giving in to the depression is not a wise option. Sometimes it is hard, trying to write a paper when mind is blank blank blank... or trying take in some dense text... I get it.
Feeling of "i have not done anything, I am worthless..." will send you spinning even further down. Do something easier if you cannot turn your mind fully on.
