Umbran said:I think the key here is time. You've got a normal workday, plus two hours of commute each day? That's 10 hours taken up with work. Then (if we're being proper and healthy) 8 hours of sleep. Figure at least two hours for the mechanicals (getting yourself washed, dressed, fed, basic house chores). That leaves you 4 hours in which to live your life on a weekday.
Four hours isn't a lot of time. It is no surprise that you've not a lot of interest in things that take up much time, but that don't enhance living itself (like game prep). Under such circumstances, there's nothing neurotic about just wanting to have some social contact without so much effort behind it.
OK, now, with a better picture, I agree with Umbran.
You're just running yourself ragged. DMing and game prep, while enjoyable, are, fundamentally more work.
My guess would be, if / when your life gets a little less zany, your interest in DMing will rekindle.
