I've been suffering from a depressive episode, sleeping excessively & having trouble studying. what should i do to help myself push through?

If 2 weeks see a Dr: Fred, A Major Depressive Disorder lasts for at least 2 weeks with problems in concentration sleep and down feelings much as you have descibed, See a Mental Health profesional if this is happening for this duration. If this is less than 2 weeks, perhaps you need to take a break from from your studies, get some fresh air, do some exercise, meditate, see a Movie etc. In short, find some stress relief
