Should I try WHM again?

Hi. I started doing the WHM (Wim Hof Method, for those not in the know) a couple years ago, it was going great. Recently, however, I started getting panic attacks, and I figured the WHM was to blame, so I have stopped doing it altogether. However, I've found ways to manage my panic attacks/paranoia, and now my brain's like "Well, since you're calmer, try the WHM again" And I'm weary it will trigger my panic attacks again? Should I give it a try or stick to what I've been doing? I should mention, I got back into yoga, and that's helped DRAMATICALLY with my anxiety/panic attacks. Which is why I'm considering doing the WHM again, because, apparently, the WHM will bring up past traumas, but yoga helps to get rid of that trauma, so in my head, if I combine the two, I'll be releasing that trauma? If that makes sense.
