Honestly, the best way for me to get out of a panic attack is to do something else with myself. I know, easier said than done. But if you can really focus on something else (it helps a lot to have someone else to talk to, but NOT about how you're feeling), sometimes the anxiety lessens. Sometimes deep breathing helps, but not always. Just reminding myself that it's a chemical outburst that will subside in a while helps a lot. That's all I got. Hope that helps!
