Yeah panic attacks suck. Def are the worst thing I've ever experienced.... When I get one I try two things.
1. Distraction. Adult Videos are the most distracting for me lol
2. Acceptance. Repeating to myself that "this will go away it always does" and imagining the time that it's gone and how good that will feel and feeling how bad I feel now and how I feel like my heart is going to stop and really feeling it and imagining that it goes away.
