what you guys do to release grief and go back to a positive mood

You sick?

Good food and beer

chocolates, nature's sunset and go home listen to sad musicks

Have you tried not being so terribad?

No for real, idk, it's kinda impossible to just will yourself out of these things in my experience. I mean, you can distract yourself, but it doesn't really go away until it's time for it to go away and you've actually managed to make things a little better.

my tactic is repression & distraction

eat waffles and icecream

look at your next opportunity or make one for something good to happen.
