Hey darlin. I've had anxiety for over a year, and it got worse than I ever imagined it could. Here are somethings that have worked for me:
1) Deep breathing. Like very deep slow breaths. 3 seconds in, 10 seconds out. It helps the brain recieve more oxygen and naturally calms you down because your focusing on your own breathing pattern.
2) Music. I have a playlist I made just for those scary-as-all-hell times where I'm panicking. I suggest "Comfortably Numb" by Pink Floyd, "Gatekeeper" by Feist, and anything by Jose Gonzalez, Norah Jones, or Devendra Banhart.
3) Very cold drinks. I found that drinking a glass of water with a lot of ice in it, cools my body down and relaxes me a little, it takes the edge off until the attack goes away.
I hope these were helpful to you hun, stay strong :)
