I don't want to share why I'm getting them, but I was just hoping to get some advice. Whenever I feel it coming on there's nothing I can do to stop it - it starts from my chest and builds up intensely, like a mix of fear and terror and panic, and it genuinely feels like I'm going to die. I have to stop breathing and stop what I'm doing, a few times I've started crying on transport or at work. One monent I'm crying then it rapidly fades away and I can return to normal.

Thankfully it's not totally debilitating but recent events have been triggering them when I so much as think about those events and I just... don't have experience managing this sort of thing. Please help me. Anything, mental exercises, breathing habits, anything at all I will try it. I hope it will just pass with time as time dulls what has happened but in the meantime it just... makes it extremely difficult to even exist.
