"It's been very therapeutic," she told MNN. "Everyone I talk to is friendly and is open to chatting," she said of meeting other gamers out and about.
".... As someone who has pretty much been a hermit, this is more positive socialisation I've had in months."
Another woman, known as "Sophia", told BuzzFeed News she started playing the game to distract herself from "the spate of shootings and bad news".
"To say that my heart has been heavy the past few days would be an understatement. But tonight my faith in people was restored just a bit. I spent most of my evening at Great Marsh catching Pokemon with a huge diverse group of people ... I'm not trying to dismiss what has happened but I feel better. There are good people in this world and its possible for us to get along."
Others have taken to Twitter to express their delight in their improved mental states, which they credit to the game.
