Gaming my way through anxiety

I'm a guy who tends to suffer a bit of social anxiety, which might be part of an overall anxiety disorder. Sometimes it's downright impossible to think about a task without being paralyzed by the fear of it going wrong. So what I do nowadays, as often as I can to try overcoming my anxiety, is to treat life like a video game. As an amateur gamer, I know the importance of gaining experience through challenges/battles/puzzles/etc., to grow as a character. Similarly, when I have to work on my master's project, or talk to a girl I like, I think of it as a task that gives me experience, which contributes to making me less anxious as a person. Doing such a thing can also count as my achievement of the day, which relieves my anxiety, and gives me a bit more confidence for the future.

What about you all? What are some of the ways you deal with any anxiety problems?
