I'm a bit reverse. Anxiety drives me towards people. Being on top of everything at work, getting into the flow - I too don't want to touch my PC for fun, but I also don't want to talk to people, or do anything that would "flush the cache" or "page to disk" all the work stuff, because I feel that once I break my stride, I won't regain it any time soon.

It's perhaps irrational, but it's something I struggle with - my perfect way of working unfortunately goes against every social expectation, life/work balance stuff, etc.
