I worry about this for two people I know with PTSD. They have tattoos of tragic things. I worry about it because he has so many years to get better, to improve in health. To look at things differently. My concern would be that looking at the tattoo day in and day out would sear into their minds how it feels today and tomorrow and be almost an anchor of those feelings in better days. Not judging. I have never mentioned it to the people I know. Just wondering if that might be an issue and hold one back in the same old feelings that you are attempting to heal.
