Totally Losing My Motivation

Yes, I know what I'm about to say is silly.  But recent changes in the online game I play has left me disinclined to continue to play.  Which is really bad.  I credit this game with keeping me engaged and at least semi interested in life during several very deep depressions.  A lot of my spare time is spent either playing this game or learning more about this game, which keeps me from obsessing about things that make me feel bad.  I am having to struggle really hard just to keep up the minimum interest in life at all.
