I didn't know that I did it until I was living with Kevin: I hold my breath. Specifically in stressful times, like when the flight/fight/freeze impulse kicks in.
Think the dentist chair, think being in the hospital, think being in a confrontation.
I did some research and it's a coping skill that many children of
alcoholics develop quirks like this. It's about making yourself
smaller, invisible, and not drawing attention to yourself.
Luckily for me I was aware of this prior to going into the hospital. I could warn the paramedics, nurses, etc that I do it as not to panic if alarms went off.
I love this song for a variety of reasons and I think of it often when I find myself in stressful situations. I love how a song can do that.
