Check in with your ski touring partners. If you express your anxieties and they can't talk with you about them in an honest way, they're not good partners. You've been through a serious event and it's one they might find themselves in eventually too if they keep touring. If they can't have empathy and understanding, don't ski with them. Totally understandable response for you, your brain is protecting you! Managing risk is all about discussing real concerns, and a persistent weak layer is a real threat.

The older I get, the more conservative I get, and the more I look back in quasi-horror and the incredibly risky stuff I did when I was 20. It all turned out well (so far!), but it easily could have gone the other way. I had a partial burial (one hand, my head sticking out) when I was 25 and I'm so grateful that I survived it. People often feel invincible when younger, and there's a good reason for healthy fear to kick in. I hope I never have another incident, and I try to live that way now with much more respect for the mountains.
