I’m obviously not a doctor, but if I were you I would not go the medication route… at least not yet. It’s entirely up to you though.
I have experienced panic attacks before and I have found that having a lot of salt helps more than anything else, as well as reducing fluids. Don’t go to the opposite extreme and refuse to drink when you’re extremely thirsty, though.
How is your salt and fluid consumption? I could quite reliably bring about panic attacks by drinking a litre of water by itself without eating anything.
