@Arcangelo I've had panic attacks in the past but not really anymore. I had my first one when I and my ex wife were going through some rocky times and I was under a lot of stress from other issues. I've had lots of traumatic experiences in my life that probably lead to me being an anxious person, but I've come to terms with it and accepted who I am and it's a relief. I look at anxiety as a friend that visits from time to time and life is great with him and without. The following has helped me keep company with my friend.
Meditation
Gym
Brazilian Jujitsu
Punching the heavy bag
Mindfulness
Breathing
Riding the wave ( visualization)
Hugging people
Talking about it
Getting good sleep
Eating right
Going out
Being responsible with weed, caffeine and alchohol
I'm sure there's more I'm forgetting
