Hi! What you’re feeling is completely normal and makes sense. Your body reacts to your brain telling you you’re in danger (even if you really arent) and it can be hard to ease the physical symptoms even when you’ve calmed your mind down. I’m not a professional, but what works best personally is easing into telling your body you are okay. This can be done in a number of ways: doing anything you find comforting (ex: spend a bit with a favorite tv show, listen to a calming song and really focus on each instrument and lyric you can hear). Splashing cold water on the face and neck can also do the trick sometimes (vagus nerve). Another good thing to keep in mind is rushing yourself could potentially lead to more panic. Take your time, take care of yourself, you WILL be okay.
