How do you deal with panic attacks?

Darina • ✨Make the result worth all of the struggle✨

So my third panic attack had happened yesterday and Im so terrified of it happening to me ever again. But I have a feeling it going to happen soon, so I want to prepare myself at least. If anyone had experienced it before, can you offer some piece of advice to make this shit more controllable? What do you usually do to calm yourself down?
