What about any kind of HoG? They are fairly mindless and you can go easy mode and everything should sparkle for you.
Hope you feel better soon!

Fishing Planet is my new go-to when Im feeling crappy. Depends on if you like fishing though. Its free at least

1. A Story About My Uncle
2. Hearthstone
3. Something Survival like Don't Starve

life is strange

1. Something where you can really kick some ass like Saints Row 3/Just Cause 2/whatever
2. Something immersive like Skyrim

Euro Truck Simulator 2

Anything with a high escapism factor, probably, like action fantasy games or sci-fi FPSes. If you want a specific recommendation, try Gurumin: A Monstrous Adventure. It's been bundled so you might be able to trade for it if you don't have it.

A shooter game.

A game with interesting/epic story or just funny, and if possible with a great OST
Unepic for the funny dialogues, really.
Ori and the Blind Forest Great OST, just watch the trailer to feel better ^^
Castlevania: Lords of Shadow serie can work too, I love their OST, and there is some epic boss fight and thank you for the N°2 ;)
etc...

The Binding of Isaac.

Neko Atsume

I will play Unholy Heights. Cute anime style Sim management and tower defense game

Classic bejeweld.

• Hotline Miami 1 & 2
• THIS ---> Very relaxing http://www.kongregate.com/games/reflexive/music-catch

Narcissu 1 & 2.

Some games that cheer me up:

• Castle Crashers
• LEGO games
• Broforce
• Civilization V
• The Sims 4

When I'm feeling depressed, I find a game I can cheat at, and totally pawn at. Most of the time for me it's MechCommander or MechWarrior 2 with cheatcodes, but any game that you can do that with, would do.. go through, rampage, and then sit back and relax :)

I would recommend some easy beat 'em up with flashy move game, like Dynasty Warrior, that 's why I like most of KOEI Tecmo games.

dota 2
well, it's a 50:50 chance you'll get more depressed if you lose the game though

Flower, Journey or ICO on PS3 / PS4

play outlast
always cheer me up
best game evahh

Grow Home, Child of Light and Ori and the Blind Forest

Southpark stick of truth you will be laughing in no time

Well I used to play grindy games with music playing in the back ( Mass Effect 3 MP, Dragon Ball Xenoverse, any MMO, M&B: Warband, GTA Online) when solo.
If by chance I find friends playing any co-op I try to join them regardless if I like the game or not.

So yeah, any game with mayhem or chill factor should be able to help you out.

thanks for all the suggestions
