I was skeptical when I read the "Funny Stuff is Good Medicine" handout. I know that laughing has made me feel better in the past, but the thought that forced laughter could make me feel better didn't seem logical. But, since this training is about trying something new (often doing the opposite of what I think might work), I gave it a shot. For the past couple of days, I've taken some time during my commute - alone, in my car - and made myself laugh.
It felt awkward at first. As I stuck to it, laughing became a bit easier. I haven't been able to go much more than a minute or two yet. And even though the laughter was fake, it did help lift my mood. I'm looking forward to continuing this therapy tactic until the forced laughter comes more naturally.
As an added benefit, laughing while in my car gives me practice with the look around technique. I can gently look around at the passing cars and notice that no one seems to be noticing me sitting in my car giggling. And this helps reduce some of the feelings of awkwardness.
