you do not need to take drugs, doctors are so quick to fill you with chemicals, many counties have a self refer to talking therapies, in Hampshire it is called iTalk, in Berkshire it was talking therapies, they teach you breathing techniques, like square breathing, breathe in for 4, out for 4, or ascending, breathe in for 2, out for 2, breathe in for 3, out for 3, breathe in for 4, out for 4 etc etc. These can easily be found online without the need to be drugged up. I suffer from chronic panic attacks, to the point where I pass out unconscious. These techniques have really helped me. You need to practice beforehand so when you feel it coming on, you instantly know what to do. Also look into mindfulness, an absolute life changer for me, helps with chronic pain, anxiety, helped me with the grief of losing my daughter, so many things! There are loads of books on mindfulness and stuff online too.
