Seems pretty active, there's usually people running TFs, mish teams, etc. There is that kinda stuff on LFG but I don't think I'd say it's full of it all day, sometimes more than other times.
I feel like you should find a mentor to help you out if you are just having issues with how to play the game
If you are truly getting depressed from playing this game I would suggest doing playing and seeking someone out to talk to. If you have a friend you could talk to them or a professional. If you are depressed please seek help (I'm not saying this in a mean way btw)
Best of luck.
