How do you fight depression?

Practicing meditation, remind yourself that the pendulum always swings, pain is a growth period and while painful the strength it produces makes you more at peace eventually.

I try to remember there is one constant thing in life: Everything changes. You will not be depressed always.

Seeking medical advice
Talking to people who can understand you
Practising sports and playing games
Have honest people around you

Pretend that I'm happy. Fake it til you make it. Your emotions are ultimately under your control that's why it works. Depression just makes you believe that everything's useless.

I use comfort food, like Pizza or Dark Chocolate..and lots of good music.

Maybe but I don't know, come here and be mean to a troll. Let out your frustrations.

wish i knew i still have it

With clenched fists!

With positive thoughts.

One beer at a time!

Bite its ear
