I have panic attacks as well. When I feel one coming on, My heart starts beating super fast. So much so, i can see it through my shirt. Then my hands get real sweaty, kinda if you had held your hand over a pot of steaming water. Then my breathing gets short and fast and I usually get nausea. There is no “cure” for them, they are life long, but they get better with age. First i reccomend finding what emotional triggers brin on your attacks. Knowing what brings them on can help you calm down. Try to breathe slowly, drink water and lower your heart rate because the higher the heart rate, the worse it’ll get. Depending on their frequency and severity level, you may have to go to a doctor and aget some anti-anxiety medicine. but hopefully it won’t resort to that. Panic attacks suck, and having someone with you to help you through them is always a great support. Hope this helps
