This has been helpful for me personally and I'm hoping others may find it useful as well! 🙂

Step 1. Get rid of all pride, ego, worries about what other people think. This doesn't have to be permanent, just for right now. Break down your walls and defenses and views on life/reality.
Become open to any new ideas/views even if they contradict anything current. In other words, just surrender for a few minutes. 

Step 2. Come to terms with death and/or the  worse case scenario for anything that could happen in a given situation. Accept everything the way it is. Again, whats the worst that could happen, death? That can't possibly be worse than panic. Let go of it all, if only briefly, and why not? Death is the most natural and normal thing that will ever happen to you. Do not confuse this with suicidal thinking, the whole point is to live, and your body WANTS to live, that's why you feel this way! 

Step 3. Understand your body is just trying to protect you and doesn't know any better. Have compassion and forgiveness for your nervous system. Use your imagination to tell your nervous system that hey, I appreciate you looking out for me. Thank you. However, everything is just fine right now. You can stop firing off stress hormones and nerve signals now, but again, thank you, I love and appreciate you for doing this, and I forgive you for being mistaken! 

Step 4. Remember that everything comes and goes. This too will pass, like it always does, has, and always will. That doesn't mean it has to be enjoyable, but you are undefeated against anxiety. Every time you've ever had an attack, extreme anxiety, or fear, you've always bounced back. In other words, you haven't been defeated. You're undefeated against anxiety. Just for right now, embrace that mistaken anxiety and tell it to bring it on, I can take you all day any day. 
Its all about a positive mindset and building mental toughness. 

Step 5. Don't expect everything to get better in 1 day. Just like physical exercise it isn't going to be the most fun thing in the world and results don't happen immediately but they will eventually. Work these steps continuously. Anything worthwhile takes time. Your brain needs time for these ideas to sink in and become your new normal way of thinking and reacting. In other words this is kind of like brain washing, but in a good, more literally accurate connotation in that you're cleansing and fixing your thought process.
We are so much stronger than we give ourselves credit for, and we will never begin to know how much we are capable of unless we push ourselves and force ourselves out of our comfort zone.
Now go embrace that shit, embrace the SUCK, and become a better you!
