You never have to do it alone.  Depression is born(e) of isolation.  Reach out to others in need you will break the spell of isolation.  We can not do it alone any way.

Isolation is bad for your problems become magnified.  And when you reach out to others your problems fade into the background.

The truth is every one has problems.  Solving them is what makes life interesting.  The only people who do not have problems are under ground.  So relish yours and at the same time reach out to others in need.  ‘No man is an island’ in the words of John Donne.
