Check out the DARE app, it has pretty good audio for instant relief and if you work through the program it will get you to the point they don’t even effect you.
Over the past year I suddenly started having major issues with them even having to go to the hospital and a mental health specialist but DARE has slowly made them a non-factor.
I know how freaky they are though so sorry that happened to you. Just know it can’t do any harm to you and you are perfectly safe it’s just adrenaline being released into your system and it’s pretty normal.
